Upgrade Custom Autopligg Software - repost

I am the owner of my own custom developed autopligg software developed in C# that I sell and would like a couple features added to it. I would also like for the code to be optimized and cleaned up a bit since it was a pretty messy job and I would like for it to be tested to make sure everything works the way it should be. The features I would like to see added are: 1) Proxy Scraper - scrape proxies from a couple sources and test them with the option of testing through google to see if they are anonymous. 2) URL Harvester to locate pligg sites, with the option of locating them based on keywords. And able to be used with proxy. Optional Features I would like added on or at a later time: Auto Wordpress/Blog Engine/Movable type/custom footprint submitter Auto forum submitter Auto RSS Submitter Please note: I will retain all rights with the source code following completion and the source code supplied is not to be distributed.
