is it eaiser to hire somebody?
That would depend on the size of the job. If it is a small job, the sackcrete would serve you well. Make a form where you want the conrete, put the sackcrete in a five gallon bucket, add water and stir with a shovel. A wheelbarrow, is another option, especially if you have to move any distance from the water source. As it dries, work the cement to the finish that you want. If it starts to dry too fast, add a small amount of water.
I think it will be the best option for you to get an estimate from a professional to do the job. Watch him do the job and you will be able to do-it-yourself next time.
