WordPress Plugin Development

I need a developer that can help create a specific plugin for our needs. ? It will take a line of pre generated line of code from Google and allow the user to paste the code into the plugins setings screen, edit the options if nessary, and then add the new functionality to their site via the pulgin. The plugin must use Subversion as its code repository and be GPL compliant. ? After the plugin is created, we will be submitting it to WP for availablity on their [login to view URL] site. 1. The plugin should work with other plugins like Super cache and similar plugins.? 2. This plugin should be able to work with WP version 2.8+. 3.? This plugin should? work with WP's built in Widget system. 4.? This plugin should generate a code snippet that a user can cut/paste into their page and post templates.
