More than happy to! I hope to get to it this evening or tomorrow. :-)
To fill you in on the process for wrapping up a contest, typical file formats are EPS (with fonts converted to outlines) and JPG, but designers can also deliver fully editable application files. After you've made your final rankings and declared a winner, you'll still be able to request revisions and will have to approve final files before payment is released to the winning designer, so you are assured of getting exactly what you need at the conclusion of the contest.
Thanks much for all your help in developing this design. I'll be back soon with more to look at.
