I have worked with international companies for more than a year with good results, specially with Philips, doing designs and flash animations for them that where translated to more than 15 languages (you can check out the designs on my portfolio). You can also check out some of my motion graphics work at my behance profile, username Cinemic. If it helps to know, the agency I was working for charged 80 euros per hour of my work, so you will get a quality designer working for you (I had to come back to my country to finish school, if you are wondering why I left).
