I have experience in PPC marketing, currently managing over $30k in Google AdWords spending monthly, and around $10k in Microsoft adCenter. I have done consulting for both large and small companies, both locally and internationally, in both low and high competition environments.
I can help you evaluate your campaign and make changes so that you are getting the highest return on your investment, as well as increase your CTR ratio. I can do this by researching the best local, long tail keywords and target the demographic that is most likely to become a customer.
I have some experience with vBulletin, but I am not a programmer. I am happy to take a look and do what I can, but if it involve any extensive coding I am afraid I can't help you there. If it is something like integrating OpenAds code, that shouldn't be a problem.
If you have any questions please feel free to ask.
