I have an online marketing business which specializes in paid advertising. I need someone who is skilled and has previous experience in online paid advertising on Facebook, Google, Bing, LinkedIn, etc. This will be a position paid hourly, maybe 10 hours per week up to 40 hours per week depending on how business is going. Above all, this freelancer must have experience in optimizing campaigns to generate the lowest cost per result. Must have proof of experience with Facebook ads. I will ask you technical questions if you are being considered, so be prepared to answer these.
