CR Clone Urgent

I am interested in developing a web portal almost like Computer repair with options for clients and for service providers, please send your suggestion and quotes urgently as we are keen to close this bid asap and get the work done by the end of Oct 2005, we want to add this portal to our site by Nov. As it will not be a public site we would only be introducing it to our own clients initially but could take it to the next level if we get good support from the developers, please note you will be bidding separately on a web portal development and a one year 24/7 support contract renewable annually. Thank you for your time and efforts.
