Remember this though: a SEO that knows his shit would never work for someone else - simply because you couldn't pay him enough.

His time is simply too valuable to work on someone else's projects, he'd rather work on his own stuff.

I suggest you start reading about SEO and doing everything yourself, because all these SEO-For-Hire wankers will just milk you for you money without achieving any results.
