Home Construction - Do it yourself Question

I recently formed up for a 14' x 50' patio slab and a 4' x 44' driveway extension. Everyting is ready to pour. My question is, how hard is it to pour and finish the concrete if I was to try to do it myself? I have never poured or finished before. Or, should I hire a professional to complete the project. If I do it myself, I am looking at 1500 - 1700 for the concrete and the pump to go over the house, since a concrete truck will not be able to get to the back of the house. If I chose to pay someone, how much am I looking at spending, and do y'all know any good contractors that could complete the work? Live in Denham Springs. TIA
