This is a separate business and should be treated as such. If more people work on it, we'll get it done faster. It actually creates more margins for errors, delays, etc. The Web is a place where you just try things and see what works I have a friend who designs web sites in his spare time. If you seriously want to have a business online, please do not go down this road and expect a thriving business.
Documentation is a waste of time and effort.
If you don't document, then how will you know what is going on, what you need to do to expand, etc. We can design the site ourselves and save money. We just want a group that will make the web pages we sketch out. I have seen examples of these sites and you probably have too. RFP's only give a general outline and you may very well be missing some key elements, plus there may be the legal issue of copyright infringement involved.
