I can see only 32 designs submitted with 6 hours left. Very few designs unlike other contests. I think the prize money is a little bit less for such a hard logo job. 4 logos will require a lot of effort and $150 is a little bit less for the job. I think!
Sorry please do not mind!

I am willing to make changes to my submission, please send me written feedback of the changes you want so that I can do a review on my work.
