Modify Eagle file

Hello! Oh, first of all, I'm in a real hurry, thanks for reading this! I have a PCB design, which I downloaded from Sparkfun. I just need to modify it for my next project. Add some components and remove some unnecessary elements. Also change the shape of it a little bit. I could do it myself from scratch in Fritzing, but I prefer to hire a professional, who will implement changes in Eagle and have an additional look at some tricky stuff, check if all traces are properly thick, etc. This would also save some time. I would like to arrange a skype call, where I provide some illustrator sketches and also explain in detail what kind of changes I need. It is a very simple project, which I think, I would complete in just a couple of hours if I knew Eagle. No time to learn at the moment. I'm also looking for a professional to hire for many future projects. Would be so great if this unfolds into success! The Eagle file is attached so you can have a look at it. It is a popular Arduino Uno shield, which must be made into an Arduino Ethernet shield. Thank you! Koka
