does anybody knows a good, internet marketing company? which is legit, with good reputation?

I was wondering if anyone here knows a good, professional, legit, with good reputation Internet marketing company.

I am trying to advertise my site www.ctatumsecurity.com I have use many resources like PPC, with yahoo, google, msn, i have paid other companies for email blasting, and top ranking, but I have lost and lost and lost all my money because they were not legit. I would appreciate if anyone of you would recommend me a good company.

Personal follow up is the best method. Get a good auto responder.
