Bugfixes and update in existing php/mysql script

I have a php script which grabs the first 100 results from 3 search engines (google/yahoo/msn). User inserts his domain and keyword(s) and my script tells him his search engine rankinks. It also keeps daily/monthly/yearly statistics in a user area. Some work needs to be done regarding fixes and updates because coder who had done it is no longer available. I am also searching for constant cooperation for future upgrades and other projects. Bugfix needed: Msn and Yahoo search engine stopped producing results few days ago. Update needed: We have to use Google api for grabbing? google results because my server was banned few days ago and i had to change server. I am pretty cooperative person and i am searching for a constant cooperator.
