are there companies that compile keyword lists on different industries? I am not talking about a tool like Wordtracker and so on. I want to go to a company and purchase an entire list of keywords based on a particular industry. I don't want to have to do any actual work except tell them the industry. I know that it will not be every keyword in the industry but I need it to be expansive. Are there companies that do this? Can anyone give me any names of companies that might do this?
