I would also concur with the advice you are receiving about "practicing" and "honing your skills" with a free site before attempting to open a paysite. When we first started with paysites, we already had many free sites, webmaster tools and avs sites on the market and this accomplished two things. First, we had a reputable name in the marketplace and second, you have honed your skillset and understand the psychology of what draws a customer in and what does not.
I suggest that you table your idea for a paysite momentarily, and build a few free sites that are profitable, then work your way up to avs sites.
