so you want someone to make a logo for a company that doesn't exist and then if you like that logo you'll hire them for $15-$30 to design another logo for the real company?

First $15-$30 for a logo similar in quality to what you've posted is offensive, expect to pay $100-$500 for a quality logo.

Second, why not just ask for examples of post work and choose someone with a portfolio you like, instead of wasting their time on a make believe logo.
