In all seriousness, you should
It's nice that you want to start a paysite, but without knowledge of the industry, it'll fail miserably. It's the same as wanting to build a formula 1 car without knowing anything about how they're built. In the end, you might come close to having one, but either it's going to fall apart, blow up spectacularly, or be outperformed by the "real" F1 cars.
Your best course of action is what I already said, take the money you have put aside for this (and I assume you have some budget available), purchase a few domains (2 or 3), get a nice webhost (important), buy some content (also important) and start building freesites and blogs.
Doing that will give you the necessary background in how exactly things work that you will get a much better idea of what's involved in a paysite.
A paysite is not just some pics, some scripts, and a website, it requires a lot of money to get started. First of all you need reliable hosting which means you'll want to go with a dedicated server. A dedicated server requires a sysadmin (and they usually don't work for free), then you will need content. Not just any content, but fresh, exclusive content. A lot of content, actually. You need pics, videos, and you need high quality. Then you need a design. Not just for the paysite, but you will need one (preferrably more than one) tour.
Then you need banners and other advertising material. Hosted galleries. Content for your webmasters. The NATS script that most people use for their affiliate program isn't exactly cheap either.
By this time, you can easily blow right through 10 grand. And you haven't made a single sale yet. Figure your monthly expenses on -at least- $5000. And you still haven't made a single sale yet.
Now in your first month, after all's been said and done, you might see, perhaps, 100 signups (and this is being very optimistic). Now say you charge $30 for a member to sign up, and assuming you do a revshare. This means that out of that $30, at least $15 goes to the affiliate.
From your $15, deduct all the processing needed to get the affiliate's $15 into his bank account. I'll assume you're left with about $12.
Now, $12 times 100 makes $1200. You still haven't made money yet. You still need to cough up an additional $3800 in operational cash just to keep the show on the road.
Maybe after 6 months you'll start to turn a profit -- but it's small, and won't allow you to quit your dayjob just yet. Oh, wait, but you do need to quit your dayjob since you need to be able to do support for your affiliates, more or less 24/7. Unless you hire someone for it, in which case your operational budget just got squeezed some more.
Now, reality: All the guys and girls out there running affiliate programs and paysites? They either started at the bottom, or they can offer something nobody else can -- such as some of the webcam girls or some of the husband/wife pairs that are capable of producing their own content which cuts their needed finances to run things by a considerable amount.
Cliff's Notes: Don't start a paysite, use the money and build freesites, galleries and blogs, start off simple, and perhaps later you're in a better position to judge what's needed to run a paysite and you can make an
informed decision at that point.
