Ajax advanced search results

Need advanced search results for my site via ajax. So when a user checks a filter the search results will adjust accordingly. Only Show Items with: Image(s) Pickup Available Offers Allowed Sort By: Total Price Seller Rating Location (top nav) Note that if a user checks multiple options the search results should alter to everything they checked. By default the search results need to be effected by the location they selected in the top bar (country or city search). The results are stored in a mysql database.
