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.
Let me see image you have. I may have to convert it to vector format in order to change size.
Final files will include vector file as main format and from there any file and size can be delivered. Revisions are included and limitless.
Best Regards
