App in C#, need forum registration function fixed, and forum search edited.

I have an app, with C# source code, and it automatically registers to forums (3 different forum platforums), and some other functions. My previous coder said it all works, but I can't get past the forum registration to find out. When it starts registering on the forums, all the browsers pop up, .. I don't want this. I want it to stay within the app, and I don't want the browser(s) visible, I only want it to say "Registering Forums...". Also, it successfully registered on 1 forum out of 300, so that's basically not working. I need someone to find out why it has such a low success rate, and fix it. The forum platforms that it registers on is Phpbb, SMF, and vbulletin. The app also has a Forum search function, where you can choose to search Google, Yahoo, and/or Bing for your specified keywords, and you can pick whether to search the keywords for Phpbb forums, SMF forums, and/or Vbulletin forums ; but it doesn't Search for these types, it only searches the keywords and returns any and everything (websites, blogs, etc..), not just forums. - So I need someone to add in where if the user selects to search for "Phpbb" forums that it adds "Powered by phpbb" after all of the user's inputted keywords. If the user chooses to search for Phpbb AND Vbulletin AND SMF forums, then, for example to find forums with the keywords "Computer, Entertainment, Parents" , then it will search for Computer "Powered by phpbb" Computer "Powered by vbulletin" Computer "Powered by smf" Entertainment "Powered by phpbb" Entertainment"Powered by vbulletin" Entertainment "Powered by smf" Parents "Powered by phpbb" Parents "Powered by vbulletin" Parents "Powered by smf" There may be a few more errors with the app (other functions not listed) after we fix all the above.. If so, I'd like to continue working with you, and I will either start a new project or I can bonus you. I don't want to give out the source code to everyone, so please state whether you have experience with this type of thing or not, so I can choose the people wisely, who I will send the source code to. Thanks, and if you have any questions please message me and we will chat more about it.
