Should I do it myself or hire a pro for a patio??

I wanted to pour an additional concrete slab next ot my current one the new slab will be approximately 6' by 10'. I just want the new part to look good against the existing patio. Should I do this myself or hire a pro? Will I be able to get someone to do such a small job?? Any ideas of what this might cost (labor and materials) would be appreciated.
