Hi,
I'm a search engine marketing (SEM) professional with seven years pay per click management experience. I've managed PPC marketing for companies like Walt Disney World, Disney Cruise Line, E W Scripps and numerous small to medium size businesses.
I've also had many third-party service relationships, like the one you are suggesting, and have developed several ways to ensure it is profitable for both of us, while ensuring the client is receiving value for their investment.
I also have a history of happy clients and can ensure that this referral, or third-party service relationship, maintains your strong reputation.
I placed a bid, because it is required, but I typically charge a set-up fee and a small percentage of total monthly spend as a management/maintenance fee (PPC optimization is an ongoing process if you are doing it right). This is the typical industry way to charge for this service, but I am also open to fixed pricing as well.
I'd love to speak with you in regard to this opportunity.
P.S. I'll PM you later today in regard to the specific questions asked in your post.
