Looking for open face software for networking, fundraising with "marathon" pages

I want to hire someone to build a website that includes, social networking membership, a fundraising database, third-party sponsorship pages with search capabilities beyond just name, and an interface with accounting software like Quickbooks.

By third party I mean online pages like you'd see for a walk-a-thon sponsorship type thing with the tally thermometer.

What open software is out there that my programmer may be able to combine using PHP and MySQL?

Anyone have any ideas?  Thanks!

You need to find a programmer and have a detailed program description written that the program can use to determine what software to use and the cost. We can suggest software, but if your programmer does not know about it or does not like it, it won't make much sense.

Most open source CMS scripts have membership functionality, and except for the accounting interface there may be things out there that will do what you want.

I think you will also need shopping cart functionality and you better plan on having a budget of several thousand dollars to start with, but that may be very optimistic.

Thanks!  I appreciate your response.
