Implement Wordpress results with Jquery (Journal)

We currently are using a custom Wordpress web site that display some custom post results with a custom JQuery animated filter. Unfortunately, pagination is required for these results, but this was not supported or implemented in the existing code. We need a PHP/JQuery programmer to go in and get the Display Filter, Post Results, and JQuery animation to all work with pagination of results. For example: [login to view URL] Under "Browse Articles" select any one or combination of filters. The JQuery will resort the results with animation. Currently, the index size for results is set to show all results. We would like to limit to about 20 posts displayed, and then implement the pagination for other pages, while still retaining the JQuery sort animation and the filter/sorting as currently implemented. Price for this work will be a fixed price agreed upon in advance of development work.
