Expression Engine - Search Module Configuration

Hi Folks, I am looking for someone who can help me with my expression engine problems. What I need: I have the module Geofinder installed but I need help to customize the form. I have events which have longitude and latitude data and a search form in which the user has to enter a city name in Germany. When he presses enter I need a little bit of coding which requires the lon/lat data of the city and passes it along to Geofinder. (If you apply add Geo as subject title or you will be ignored) Also I need a "normal" keyword search set up which includes searching in titles and in one other custom field. I don't need any design work done, I can handle the tags in the result templates myself. The problem is really just setting up the search-forms and the code behind it. If you think you are able to do this good and fast (1-2 days), you are my guy. Thank you very much.
