Hey AMG
Welcome to the pond. My advice would be to start out building a three page site that pushes to your cam shows. Most cam sites have an affiliate program. Make sure to sign up for that and put all the linking codes in to link direct to your bio page. I would also add a place to sell custom sets, and videos through epassporte. Once you get this site going and pushing some good traffic then I would merge to a paysite however not before. The reason for this is simple; if you can learn how to market yourself and learn how to do traffic with just a three page site you are saving yourself a lot of time. Running a paysite is tough. It takes a lot of work with updates, and photos shoots and marketing. I would stick to marketing and then when you get that down move to a paysite. That way you are not putting a lot of work into building a huge paysite until you have traffic to sustain it. The biggest thing in this business is traffic. You can have the best site in the world but with out traffic to sustain it, its all pointless work.
Also this is a great place to learn how to do your own traffic. Check out the newbie section and the blog section for some extra help. I do a lot of free site submission too. If you want to learn how to do that let me know.
