Customize a wordpress plugin for the Classipress theme

Hi i need somebody to customise this plugin for me: [login to view URL] at the moment when using the plugin and doing a search the url in the toolbar will look like: [login to view URL] i need it to look like this if possible http://www.mysite.com/search/category=all/bedrooms=4 where "category" and "bedrooms" will be custom fields used with the search, it doesnt need to be exactly like that but if you can do something similar let me know, i want it to be as short as possible you can see the search on my blank site [login to view URL] (on the homepage under slider) also classipress comes with a (distance search) built in to the refine search, i would like this (distance search) intergrated with the plugin so i can add a distance select box in my custom forms. YOU MUST HAVE KNOWLEDGE OF BOTH WORDPRESS AND THE CLASSIPRESS THEME BY APPTHEMES please right appthemes in your proposal to show you have read my requirements thanks.
