Here's the bad news - I originally wanted to use this to vet some art services before we hired them for full projects. The services we were looking at are no longer in business. Moreover I don't need to go through a vetting process anymore because we eventually ended up hiring some amazing top tier artists on our own. These artists are nose to the grindstone, making sure the battle grid is online as soon as possible and cannot be spared for the logos.
Here's the good news. You guys have been patient. There's an auction house on the Something Awful forums that people go to for logos. I'm spending $80 of my own cash so I don't drain the company resources and can still provide you with the logos.
The first two logos are queued up, and as per GonFreeces31's request I'll try out Icy's idea first. The auction will be posted shortly on the something awful forums and the winner of the best picture will get $40 next week.
edit: The auction is online
but requires a something awful account to view
