Concrete Pouring Questions? - concrete bathtubs diy

I need a 16'X23 'garage concrete floor (the dirt floors and a basement wall is already), plus have a foundation 4'X7' is used to build a second floor master bathroom renovation in the whirlpool. I must have the correct thickness of a garage floor in the Northwest know, and a foot support of the Foundation (1500 pounds when full) bath. I would like a foot bath, not only to an extent, but an area so that they are not as deep, with screws and invents. I need estimates for practical work experience - as far as I heard one, the work of $ 1600 for 5-7 cu.yards listening to right it?
I can create the form on the tank platform support, but do not know how to do deep. I do not know how deep the garage was not the "ISP" the specific job.
I would do it yourself, saving work ... How difficult is it? When you receive the car and some friends in Wading, it is difficult to align everything correctly? Thanks
