Need VB.NET Code Optimized for Speed

Hello everyone. I have a VB.NET project file that is meant to scrape emails. (it also has a few other personal tools, but those are irrelevant towards this project) The section I need optimized is supposed to scrape emails from Craigslist. It works fine and all, however I need it to work faster. Here's what I need you to do. You MUST be a very skilled .NET developer. First of all, you will need to analyze the code and actually understand all that is done. After analyzing it all, and getting to know the interface and code together, you will need to develop a way to effectively thread this over a customizable number of threads. (there will be 1-10 checkboxes in the setup tab to select how many threads you would like to use) You will most likely have to modify the code a good bit and comment it out, as my current code is very sloppy and not very high quality due to the speed it was done in. This program must work perfectly - if you have another method of scraping craigslist emails that may work better, go ahead and include it. It must have the options that I have on it now, plus any others that you would consider productive to the project. (I tip well) So, in short, make the project your own, do what you have to. I want all cities included in the program, as well as all categories and at least the features I currently have included. (plus anything you would like to add) I don't want any other forms in the program modified - just Form 6. (which is the Craigslist Scraper) If you can do this, please give me your bid and the time it will take. Thank you, and I look forward to your bids!!!!
