Need a software..

Hello, I need a desktop software to scrape google suggestor. I need multithreading software and private proxy support. I will have list of keywords in a txt file, I will feed in this keyword list, feed in the proxy, set the threading and click start. Then software will scrape all the google suggestor up to 3 level, meaning, it will use the keyword found and search for those also, and then search once again and get all the keywords possible. I have this software alredy, I input about 200 keywords and click start and it generate me about 30,000 keywords, then when I put new list of of keywords to try again, software is not working and it's because the software doesn't support proxy. Now, I need a software that is alot faster than what I have, it should be multi-threading, I would use around 100-200 [login to view URL] will use 1 proxy/thread. I need to generate millions of keywords and I need a powerful software.I have powerful server for it. Happy bidding. Thanks
