Advanced Search and other PHP/AJAX development work

Please note that larger purpose of this effort is to find a developer who I can continue with in long term. I am looking for a person who can spend about 15-20 hours per week from home. The ideal person should be one who is familiar with PHP/AJAX/JSON etc. and has all the set up at home (PHP/mySQL). You can login in here at [login to view URL] username/password - demo/demo 1. Go to edit partner profile on the right and then there are search features that need to be worked on. (it currently has issues) 2. There is a signup form that currently has issues that can be fixed. I would like that new users are able to sign in with ‘Login with Facebook’. 3. There is referral system that is in place (refer someone from the link at the bottom right). I would like to extend it to ‘Like it on Facebook’ and they are able to get referral points Few features like the above need to be worked on. These are just examples and there is plenty of work. Please do not bid on the project unless you have done similar projects. I will not be able to respond unless I find a very close match on your demo link. Template replies like 'Ready to start the project' or with 100's of links will not be responded to. Show me the work and you and I are in business. Please quote for about a week of work which I am hoping is around $50 or so. The rate varies with experience. But keep in mind, it is long term. I currently have someone working on this arrangement and it has worked out for me. I am reasonable in my expectations (above items cannot be probably finished in one week). Thanks for your time.
