Php - Mysql coder for couple hours - 2

Hi, I have a website with some filter list to be able to choose a product. I want to be able to know how much products i will have when i click on each filter. For moment, i am able to know how many product each filter contain and if i choose a filter, how many product will appear if i choose one of the other filter (multi filter is working). But if i have two filter, i am not able to know how many product exist on this two filter and on other (to be able to count well). That why i am looking for a php programmer who know well mysql. The job wil be to work with me on this project (I think 2 or 3 hours for a good coder). I want somebody to be avalaible on some messenger (msn, gtalk, skype) to work with me. I will procure the code and assistance. As the previous Freelancers was not able to make the job, i propose again this project.
