Design 20 Post Cards

I would like to have someone design 20 post cards/puzzles. I will require all the original files in CMYK format because these need to be printed. I require very detailed work and I don't like cartoon style. Please see this link for an example of work that I like http://www.amazon.com/gp/reader/039921920X/ref=sib_dp_pt/103-6229186-4325401#reader-link PLEASE QUOTE ON ALL 20 POST CARDS, NOT INDIVIDUALLY. I WILL PUT THE MONEY IN ESCROW THROUGH FREELANCER AND THE MONEY WILL BE HELD THERE UNTIL THE PROJECT IS COMPLETE. NO PREPAYMENT BECAUSE I HAVE HAD PROBLEMS GETTING FREELANCERS TO FINISH THE WORK. PROJECT MUST BE COMPLETED BY JANUARY 5. Those who provide mock ups will be considered highly. 1. Snowman and a tree (not a christmas tree, just a pine tree) 2. Christmas Tree with presents. 3.
