Make a topic, write down every aspect of the coin you want to be created and ask for quotes.
Pick somebody that has had some positive feedback with this kind of work, and send enough funds to cover the creation process to a trusted escrow. Once the dev sends you the sourcecode, compiled wallets,... the escrow can release your funds to the dev
