He Ordered Card/Logo Design and we've decided about a upfront 50% and I've stopped to take the other orders because I don't like to let the customer wait too much or even work on two projects to put my full effort on one for a High Quality Service Anyways he ignored me without giving me the 50% for like five days and then answered with I had deadline and again he's not answering

P.S:
That's from the sunday tho.
Rudy: i am working on it
Rudy: paypal stuff
Moe: and when you are going to be ready?
Rudy: this evening

I don't recommend to work with this guy.
