Need google serp checker (website rankings checker)

Hello, I need google serp checker. I alredy have a software name cuterank, it does the job but it's very slow. I need to check serp of 50,000+ pages daily, it takes hours with cuterank, I need it done in minutes. Software will be multi-threading and it will support private proxies. I will have a csv file, column A will have list of urls and column B will have list of keywords. I will have private proxies in this format (ip:port:username:password) in txt file. Software will run the number of thread = number of proxies. If there is 100 proxies, multithreading setting will be 100. I will be able to set how many seconds to wait before searching for the next keyword, this is for 1 thread only. For example, if I have 100 proxies and I set it to wait 20 seconds before searching for next keyword, software will check 100 urls every 20 seconds. Need a desktop software. I have low budget. Happy bidding. Thanks
