Fix my web scrapper

Hello. I have a web scrapper that scrapes data from multiple online retailer. Software gets data such as price, stock, title etc.. Three days ago, one of the suppliers([login to view URL]) has block my scrapper. When software runs, it is able to pull data only for the first few links. After the first few links, software is not able to pull any data for the rest of the link as hayneedle detects that it is a robot trying to gather data from their website and they block it. I hired a programmer a day ago to do the job to avoid detection but he could not do it. So please only bid IF YOU CAN DO IT for sure. The programmer tried doing ip rotation but it did not work. It is not an ip problem. The programmer also created a one second delay for make it run slow and that too did not work. There is something about the software that hayneedle is able to detect that it is a bot trying get data. Job conditions: I need a programmer expienced enough to overcome that detection and make software work and pull data without getting blocked. You will only be paid IF after working on the project, the software is able to run and get data without detection. If you do the work and fail in the end and not able to do it(accomplish task), you will not be paid. So please only bid if you know for sure you can do it.
