Hello!
I'm so happy to hear that you've gotten the majority of your work finalized, and you're satisfied with it, and it seems you have only a little left to do!
What you're looking for is simple, and you're indeed correct; This is a job that shouldn't take more than an hour.
Something I would like to recommend, is even if you're not going to be using myself, I would ask the artist to do this project in Illustrator, doing the project in something we call vector, not pixels. Doing this is vector will allow you to use the finalized product in any size -- doing so in a pixel based program (Photoshop) will leave you with little customization room when it comes to sizing this (Should this image be as tiny as a letter head or as large as a store front sign).
Beyond that! I would of course like to mention that I'm a Graphic Artist! I worked for several years to obtain my degree and graduated in 2015. I have a steadfast knowledge of the Adobe Creative suites (Photoshop/Illustration/Aftereffects/etc.) I would love to get the chance to expand my portfolio beyond what I have and gain some more professional pieces to preview for later works. This particular job seems like it'd be perfect for me, and I would love to leave you satisfied with my work! I'm available at most hours of the day by phone or by e-mail!
I look forward to hearing from you in the near future, and with you the best of luck in your up and coming business!
