Hello all creative members. We announcing a contest:
We need create a signatures for our campaign.
Please write us your price for the services and your portfolio of signatures you been made before.
Contest winners will be announced after 5 days.

Instead, make a thread where you offer BTC for the best signature so that every creative person gets a chance.
As said by other users, look at those links and see the threads of other announcements. Since you failed to reply in time, i assume it was a hoax and you were about to scam people. I do hope you stick to your words.

I think the best choice will be that you announce a contest like this https://bitcointalk.org/index.php?topic=1530534.0

It is a go dexample for starting a contest for signature designs, in there all the details are provided.

Yeah that is a correct way of making a signature contest thread. Here, OP didn't care about providing details about site himself.  Also you can also get sometime a nice signature from guys who never made it.  So i don't think you should worry about past work / portfolio in contest . However, I myself agree to portfolio/ past work point provided if you are not making it a contest and want someone individually to do it for you.

Here is my signature designing thread: - https://bitcointalk.org/index.php?topic=1410437.0 
Making a signature pack @ 0.05 BTC.

Maybe you can escrow the prize? So we know if this contest is really running.
