Hello,
I'm Arsen and I would like to offer my designing skills. Please, first take a look at my portfolio, here at Freelancer to see my work. If you like what you see, we can continue to discuss about project you have.
I have worked for one French company similar job and I know that sometimes those PDF's can be very hard to edit. I don't do them in Photoshop but in Corel, Adobe Acrobat. Results are good.
I'll ask to see those files and to try to edit them before I really start job. If I cant do them properly, I'll inform you so you can search another designer. My response will be in few hours, you don't have to wait for long.
Best Regards
