There is alot to consider when opening a webcam site or webcam studio.
Obviously the more that you can do yourself will be the hardest, but it would also be the most profitable and the most rewarding since you would be relying less and paying more to 3rd party companies to help you to achive your goals.
For example, becoming an affiliate of an existing webcam company can be the easiest, but of course this is actually the most expensive. As an affiliate, you have to spend your time and money promoting "your" site by sending all of "your" customers to "their" website, payment processing, and models, all in exchange for a commission. The commission you are usually paid is often very low, but more importantly, all of the time and money you have spent gathering customers is completely lost because all of those customers, their data and repeat sales, belong to the company you are promoting, and not you.
If you want to keep the rewards from all of your hard work, you are always much better off to doing as much as possible, yourself.
Here are some basic tips, in no particular order.
1. Buy a good domain name plus a couple of variants of the name. Do not buy a name that sounds like, or is similar to, any other domain or company. This will only server to remind your customers and models of your competitor and create potential lawsuits.
2. Look around for some good videochat or all-in-one software to power your website. Buy, rent or lease a software license that gives you full ownership of the data with flexible terms.
3. Find a hosting company to host it for you, or host it yourself on AWS or Linode if you know how. Like software, find a hosting provider that is flexible, and that can provide good support for you. Don't overprovision, meaning, don't go crazy renting dedicated servers at first as they are almost always unnecessary. Instead, go for small Virtual Machines - they are cheap, fast and easy to manage, and can grow quickly as your requirements grow.
https://tmdhosting.com is my favourite.
4. Go with a payment processor like CCBill to start. Yes they are expensive at 14.5%, but they offer fantastic support and wide variety of tools including an easy to use and trusted affiliate program. They are flexible, and offer support far beyond technical.
https://segpay.com and
https://epoch.com are also very good. If you have a merchant account, you can use a gateway provider instead such as
https://netbilling.com (my favourite).
5. When it comes to models and broadcasting, you can hire models to work from home of course but, if you have the means to do so, you may want to consider renting a location and hiring models to broadcast from there instead. A Studio location provides all kinds of benefits to both you and the models. For example, you may want to build themed rooms with high-end lighting, cameras and computers to deliver a really polished video stream. Models may not be able to broadcast from their homes, making your studio an attractive solution. Locate the studio near a college if you can, and models will be lined-up around the block to work for you.
6. Buy small amounts of advertising from several different traffic providers, to test each one out. Make sure you hae a dedicated agent that cares about what you want to do and will work with you to fine-tune the performance of those ads.
7. Don't underestimate the value of SEO. Make sure your site is setup to allow public comments and communication between users and models that search engines like Google can crawl. Add a blog and take full advantage of social media too. The more organic traffic you have, the better.
8. Train your models to treat your customers the way you expect to be treated, with attention, courtesy, and respect. Most of your customers (50% at least) will be shy, introverted, without a spouse, disabled, or worse. The more respect that your models can treat your customers with, the more likely they will return and spend money. Since there are many videochat sites online today, a little TLC will make your website stand-out from the rest.
9. Don't hire just "any" models. Be very choosey. Bring on only models who have the look that you personally like. If you like redheaded girls with freckles, hire them and feature them on your site. Whatever it is that you personally like, 100k+ others like exactly the same thing. Take advantage of that niche.
All of the above can take a considerable amount of time, but the demand for attention from pretty models is HUGE, and the money to be made in this arena is limitless. If this is the area you want to get into, go for it, and don't let anyone get in your way. The rewards are exceptional: Very, very good money, Very low cost after startup, and even alot of fun.
