List of SEO Companies

I am looking for a Database of SEO Companies with Contact emails from U.S and U.K . I mean the companies that offer Search Engine Optimization and Rank Building Services. I don't have a problem how you find this info. You can use Internet Search, Craiglist, Yellowpages or anything out there. I need exact contact information. If any of you guys have this list already with you, then also i am interested. If you are from U.S or U.K you can even search in local business directories. Please do not provide junk data. Each entry will be tested manually by another team. So i prefer to get the data as batches of 200 or 300. Needs to be submitted in an Excel sheet with the following fields. Company Name Website Link Contact Email Contact Person WHO IS Email My Budget is not that high for this. So Please get me a good Price also.
