Finding one is easy but getting them to do something for you in a certain place and time can be more difficult.
You could try asking yourself these questions:
Are you looking to hire someone or hire them full time or make them a business partner or maybe chat with them for an hour or so?
Where do you need the work done?
How much are you paying?
What kind of work needs to be done?
How long does it take to do?
What specific qualifications do you require?
