I have sent you a PM. My company will be more than capable of providing you with this
We've recently just built
http://goingoutfit.com which has hundreds of features and was built using Ruby on Rails, however we're capable of PHP also. The website was made in roughly 7-8 days and about 6-7 hours work per day, so the development time is a very quick turnaround if you also need delivery of the project soon.
To give a better estimate in price, will you be providing a design for layout of the system or would you need that also, and also how well polished you'll need the system, a full feature list or a view of the design would indicate what you have in mind.
Thanks
