Hello, i'm an Adwords certified professional with 3 years of experience. I run and manage multiple campaigns at the time for my clients, on and off freelancer and would like to discuss your project in depths if your interested in hiring me. My English isn't 10/10, more like 9/10. But i get things done in a proper way and without any major problems. I use US English so if you want to use some phrases that are native to Australia we should consult on those.
About the work hours i didn't know what to put it cause im not sure to what extent you wish to outsource work, how much of work there is, and what the size of the campaigns are. Like i said, if you have any questions message me back, i'm always glad to prove my expertise in the field of Adwords :)
Cheers
Tom
