Looking For An SEO Company Or Strategy That Works

I have a basic plan which is to find an SEO company that actually works and can prove they work, almost regardless of the cost, as long as I can put a commission on it and sell it to my clients.

I get many website owners every day contacting me about my services, and I often recommend that they should do SEO on their site, their Facebook page, their You Tube video, etc.

I tried running my first SEO campaign, and it was going well, until the client went and bought hundreds of spam links from a crook on Odesk.

The site hasn't recovered, it was on the first page, first on the first page at one point for skin whitening products, then it fell to page 9, and the client isn't even listening to me about publishing regularly on the site, so it's unlikely to recover.

The Facebook page I made her is still ranking well though, that's one thing that really works for SEO, and I have a few Facebook pages of my own that I'd like to rank.

As I said, I just want to know a company or a few companies or strategies, something I can outsource or do quickly or fairly cheaply so I can then sell it as a service.

A guest posting service, or a well established big SEO company that's never gone wrong. I don't want any affiliated replies, unless you can easily prove that you represent the company I'm looking for.

I don't want any fast solutions that rely on link velocity, I want well written, quality, lasting back links that will keep working even if the campaign stops.

Any suggestions? If I can do this, I can probably finally get rich through building a solid residual income by selling a much needed service to my clients. It just has to work and work well.
