So, let me understand this correctly:
- You're offer hosting services.
- You're offering Invision Powerboard automatically configured.
- You have no way to actually offer this service to people.
You've not really thought your business plan through, have you?
Might I suggest you find a website that would get you in touch with a freelance programmer... I think zend.com have a freelance/short term contract section. Mind you, it'll cost you a fair amount. If I were pitching for this sort of thing, at a rough estimate of 2 weeks work, you'd have to pay in the region of £5000 (US$8000).
