Customizing Wordpress Custom Categories and links - repost

Hi, I have a directory builded on Wordpress. When someone submitting listing,he has to select location and category For example if he select Location: "Chicago" and Category: "Internet",the listing will be listed under 3 categories: [login to view URL] [login to view URL] [login to view URL] Now i have 3 things that want to customize: 1st. is breadcrumbs - the breadcrumb structure must be me as follow: Location > Sub-location> Category> Subcategory>Sub-sub category (if you contact me i will give you more details about that) 2ond thing is to to have sublocation and and subcategories links on parent pages (if they have listings) Example: if a listing is listed under location: USA> Chicago and categories: Internet> Websites > Directories On main location page( USA in this example) must have a links to sublocation Chicago and to main category: Chicago-Internet When you click on Chicago-Interne,there must be a link to Chicago-Websites and so on... 3th is to load the sublocations and subcategories in new field ( prefer with ajax) I hate programmers to say:"You didn't said this or that" ,so i will tell you that way: THE PROJECT WILL BE DONE WHEN CATEGORIES ARE JUST LIKE I WANT THEM,NOTHING MORE,NOTHING [login to view URL] YOU DON'T LIKE MY TERMS -DO NOT BID.
