Design an Advertisement

I need an ad for a community newsletter. The ad is 4"w x 5.5"h (1/4 page). I have done a mockup in Microsoft Word, and saved it as a pdf. The printer needs a high res (300dpi+) file. My mockup needs a bit of additional work but is 90% just as I'd like it to be. I am seeking a graphic designer I can email my portrait photo, logo and the mockup, etc and have a brief conversation with so you can prepare the ad to the printer's specs. I'd like to go hourly since I imagine this to be a very small job. I am planning other marketing and will need more help in the future, and would prefer to not be doing mockups but instead handing off my graphic design to a pro (I did the mockup b/c I was told the in house graphic dept. could create an ad for me but what they provided was not even close to acceptable). I plan to run ads in other publications as well as print marketing materials so this could be the start of further work. Thanks!
