Your a lot more skilled then I am Bentley. I want to try working with concrete, but I just picture it turning out really bad. Something to consider for smaller jobs though is that Harbor Freight sells cement mixers for less then $200 before coupons if you wanted to deal with mixing your own. I considered renting one, but at that kind of price I can afford to buy one and figure out what I am doing, compared to renting. The 80 pound bags are horrible to move, but can deal with most of that with the front loader on my tractor thankfully.
