Sketch on adobe illustrator

I am a product developer and have already had a package for a new plastic hair barrette designed via a different graphic artist. On the back of the package, among other things, there is a photo of the barrette in the open and closed position. On the photo the words "Open" and "Closed" appear. I would like to forward this file (that I believe to be on adobe illustrator) to an artist and have them to replace the photo with a drawing of the barrette in the open and closed position. The drawing would need to reflect some slight (easy) changes from the product featured in the photograph. I am told that for me to ultimately use this sketch on my package, it would need to be done in Adobe Illustrator. I will also need a sentence or two of verbiage changed on the package. Finally, this project needs to be completed by next week. Thanks for considering this work. I look forward to hearing from you. Budget is $40.00 - $200.00 US.
