Where can I find a credible company to hire to build links for a site.?

I want to find a company to hire to build external links for a company. I have a good budget and need to gain about 40 to 50 quality links a week. Anyone know a good company or agency?

While I would like to rep my own company, that is not what yahoo answers is about, so I am going to swallow my tongue and suggest another service. You want to stay away from gimmicks, or people that say they are going to get you a ton of links a specific way. The trouble is, to look natural you want links from everywhere. That includes article directories, link directories, blogs, forums, comments, video, and social bookmarking. Go over to getafreelancer.com they have an affiliate program that I could make money off for recommending you but I wont use it here. Open a project and look for a freelancer. Look for one that has an all around plan the includes all the above mentioned over several weeks or months. A decent one will cost at least $500. Keep in mind that this is a generic answer based on very limited info given by you. The downside of SEO is that you really dont know until you use them or know someone personally who has used them.
