Ann has been designing everything for the game we have been working on. She is a platinum designer in 99designs. She can help you with graphics. Ann also designs cool logos. If you need some designing done in tight budget, feel free to contact her.
Here’s her email : ann[at]imagnity[dot]com.
This is not going to be free but she promised she won’t rip you off. After all, we are all indie developers with light pockets. You can see some of her work below or get some free designs from here.
