The basic functionality of the website/system that I want you to build for me, is very similar (technically speaking) to www.linkedin.com.
There will however be substantial differences in my implementation, but for the purpose of bidding you should bid to build a clone of this site as if you have the skills required to build a fully functioning [url removed, login to view] clone, you will be qualified to work on my project, the scope and scale of my project will also be similar to linkedin.com.
Demos of similar types of php/mysql social networking work that you have created will be required.
If you believe there is already a product out there that can form the basis of this project and you customize it, then that’s great, just as long as the legal rights to use the underlying code can be obtained.
Once I have reviewed all bids a shortlist of developers will be sent updated specs.
