I've sent some proposals in your form.
I think that an exchange today should handle more than just Bitcoin.
Good luck!
God,why you guys don't read ? Like you're a legendary member,least you could was just read two comments above.The bounty is over,OP ran away with the funds.You could have saved yourself some time had you read.
I submitted the form and my suggestion is cryptobrazil.
I couldn't come up with nothing more original but that name came up first on my mind.

Wish you well on your journey.
And does it feel to get disqualified from the competition ? haha there wasn't any.
