Craigslist Graphic Design

So I've been doing my own graphics for craigslist and I know my graphics are pretty darn good. However, my company pays a pretty penny for my hours during the day and therefore, I'm hoping to find someone who can do great design in a timely manner and for a price less than my cost to the company. I will only consider applicants that submit to me examples of previous craigslist artwork. Please quote me for 12 total designs basically 2 designs for 6 cities but they all need to look different. I will provide content information and some elements. Also, if you are a designer I will not accept designs that infringe on copyrights. If you use vector elements or stock photos they must be properly licensed. I will give whomever I hire access to many design elements and stock photos that I already have... I will need these designs turned around in 24-48 hours and your quote should include unlimited revisions until I'm happy but if you're good it shouldn't be more than 1-2 revisions per design at most.
