Custom module in Drupal

I need to tie three modules in Drupal to work together. In Drupal , there are three modules. I already have them installed and fully functional: 1. Faceted search <[login to view URL]> 2. Geonames Cck <[login to view URL]> 3. CCK Facets <[login to view URL]> Currently, CCK supports only text/date/some other CCK field formats, but not geo_cck. Geo_cck stores data in lat\lon format, and geonames API (<[login to view URL]>) is available to perfom all kinds of searches. I need a plugin to add geonames_CCK as another CCK type to CCK_facets so that I could add then as a facet for my FacetedSearch. Then, I could search my nodes simultaneously on several facets: e.g., all books tagged "Love story" who "lives in Russia" . This plugin should be developed on your machine, and as a deliverable I would like to receive a code and a note on how to install it. I will install it myself.
