Setting up contextual advertising in Yandex/Google

I am a beginning specialist in contextual advertising. I plan to take up this line of work seriously and for the long term. The priority is high-quality setup of Yandex Direct and Google Adwords advertising campaigns. Since I do not have much experience, I am ready to work on several projects in exchange for a review or for payment at the client's discretion if satisfied with the result of the work. I do the work manually with minimal automation — for which reason the deadlines for completing the work may increase somewhat.
