PHP / Ajax / Javascript programmer to amend search filter

We are making some amends to and existing website and are having problems getting our existing provider to complete changes in a timely manner. The changes we need made are URGENT and ideally we would like someone to be able to start work straight away and work over the weekend. The search filter is on the left of the following page [login to view URL] It is meant to function a lot more like the one shown on [login to view URL]:Min,Max~0.5 We also would like to make some minor CSS changes to the style (please be aware that we have been warned that the CSS on the site is a bit of a mess) A full brief will be provided once we have viewed your work. To be selected for this work please give us the following details: - Time estimate to complete the work - Confirmation that you are available to work within the deadline - Examples of previous RELEVANT work If this job goes well we have plenty more work. Thank you for bidding and taking the time to read this post :-)
