I'm new to the industry. I kicked off my first tube site a little under a week ago. I'm receiving roughly 5k daily from organic (Not paid) traffic and about 80% of it is unique visitors. My top regional tiers are the following:

United States
Great Britain
Canada
France
Germany
Australia
Netherlands
China
Russian Federation
Sweden

I've looked into businesses but haven't sent anything yet. I want to go the route of finding advertisers to pay a monthly flat rate. I don't want to deal with ad networks, from my pass experience they pay garbage and skim off impressions/clicks.

My questions are, with what I have now how much should I charge, or how much of a minimal offer should I take from an advertisers offer price?

Also, I am going to send out emails to advertisers but haven't a clue on what to write in them to sway potential interest in my business?

I'm relatively new at sales and lack the knowledge or experience at the moment. I have many ad slots on my tube site. I'm not looking for a bazillion dollars. Just enough to sustain and improve my current living conditions until I either find something new or improve the site. I'd like to get into the adult business community more, find new contacts and potential businesses for my growing site.

I've worked tirelessly building the site up from scratch this includes the script, programming and gaining organic traffic.

I'd appreciate the help from the professionals and that's why I'm posting here on gfy.com these questions
