Ok, it seems you only scan for the price, and don´t read anymore....or you don´t understand my english at all.
In my 10 years as a graphic designer, I have made hundreds of proposals and taking part in a lot of contests, and only being paid if the work was finally done.
That´s the risk of this business.I was going to pay the right cuantity if there was a winner, not only the 30$ for the initial idea.....
I have received 5 emails of people interested in giving me a proposal with some design ideas , free of charge...Thank you.
You have to think about it...there are people, top level designers, in India, Argentina and other countries, who earn 5-6$/hour....Do you think, it cost more than two hours for making such a concept?
Now, seeing the ages of you (20, 15, 16....) I begin to understand everything
You want, as a teenager amateur designer to earn professional hourly rates.
It´s not my problem, if you want to charge 6 hours x 30$, for a work that can be best done by somenone professional in 2 hours at 5$/hour.
I cancel the contest and good luck, you will need it.....

Thanks
