I Want to put my work on a T-shirt is there anyone that can vector my sketch for me? im willing to pay Via PayPal. It would be much appriciated if it could be done and the PSD sent to me. something along the lines of these colours :
A vector would be an illustrator file, so I think you need to make sure first you have the program. Otherwise you won't be able to resize it afterwards. Doing it as .Psd would mean doing a vexel, but that implies that you can't make it any bigger than it is, without losing it's quality.
You can open .Ai in Photoshop and resize without a problem. I do it all the time. You just wouldn't be able to save it as .Ai again.
I, too, am also interested. However I would only do it if I knew I wasn't competing against others to hand it in first to be able to get paid. I don't want to spend time on something to find out someone's beaten me to it.
