Thanks for your PPC/display offer. Post your elance details (or your website), as I will most likely be hiring someone from there or a marketing agency.
I didnt mean you hire me, if I can be of any help to you in specific problems you have i might be able to help there (free of course), Ive been doing it on a daily basis for years for myself and clients.
I have a website but its in spanish, so no use to you, I never had to present credentials before to get clients though, PM me if I can be of any help and good luck with your project
