Best advice once you find your niche, Shoot your own content, don't pay models per scene, pay them a flat rate for a shoot. This way, you maximize your $$$ and stretch it. This is also advantageous as you will have exclusive content and not recycled content that have been around on other sites. No offense to content sellers.
Find a good hosting company and start with a basic package. Exchange your links with those adult link directories if you don't have a big advertising budget just to get some trickle in traffic. Use the rest of your advertising budget to buy traffic from the buy sell section of gfy. Be smart about the type of traffic, buy pay site member traffic if you have a pay site. Stay away from link farms as your site will get penalized for being listed on those sites.
Be patient, work on promoting your brand. Don't expand quickly. It's about quality rather than quantity
