Being 16' wide, you are going to need a helper, but this is how I would suggest tackling this:
Set the tops of the forms rigidly and as accurately as you can. Don't under estimate the force created by the weight of the 'crete - stake the sides well. Give consideration to drainage and slope when setting the forms - either plan on a slight crown across the width or a slight slope down the length. Start the fill in the back and simply fill the forms, moving the crete around with shovels and a rigid tined rake. Tamp it down well on the edges and in the corners with the rake to pack it and remove any voids. I suggest trying to tamp all of it - as you are spreading it you will introduce air and voids - work it up and down with a rake or stab it with the shovels to settle it. Over fill the forms slightly. After the crete is basically where it needs to be it will need to be leveled and smoothed. The pros can float it because they have the experience to do so, but even the experienced guys can leave low spot and high spots. I would suggest that you take a board (in this case a 2X6) -actually it might take two 12 footers screwed to a few backing boards or pieces of angle iron to make a stiff 20'+ long board that is straight and smooth on one edge. You can belt sand a slight crown across the length or just leave it - it will bow and curl when you are using it and as long as it does not sag, your driveway will be relatively flat.
After you get about maybe 6' to 8' roughed in, take the board and set it on the top of the forms at the back edge and using a slight sawing motion, advance it down the form relatively slowly. You only need to 'saw' it maybe 2" or so. It would be helpful to have a third person to help fill low spots or remove excessive material as you are doing this. Keep the tops of the forms clear to help keep the surface as smooth as possible and try not to mess with it any more than necessary - the more you screw with it, the more of the Portland will be pushed away and you will be left with a relatively rough, exposed aggragate look. Your first pass with the board will not be perfect - it usually takes a tleast 2, sometimes 3 passes. After it is smoothed and flat, let it sit and move forward. It might be helpful to mist it lightly with water every once in a while to keep it somewhat damp, but be careful not to hit it with enough where you begin to form puddles - this will create problems, too.
Basically - that's it. You do this the entire length of the drive. Come back with a stiff bristled broom after maybe an hour (depending on the temp, etc) and drag it across the surface (again - only one or two times - MAX). Don't try to broom it until it has set up pretty well - you will tend to want to try to broom it too early. The surface is still usually soft enough to broom for at least an hour after it is poured - again - this depends on the temperature and how old the concrete is. Sometimes the drivers will stop by their house, Dunkin donuts, the gas station and the grocery store before the crete makes it to your place, so each load might be a little different - you have to judge each dump seperately. If the load is dry, mist it while you are shoveling and raking - don't wait until it is leveled out.
There's more to it, I guess, but this is all I can convey without writing a novel. I am not a pro at this. I have poured several pads and these are the methods I use when it's a DIY job - otherwise I will just pay someone as concrete is expensive and you don't get a second chance to make it right.
Duty calls - I will check back in a little bit.

I do not have the extra money for him to finish it. So I guess I will have to finish it myself. I have poured and finished concrete with a broom finish, but not with a smooth finish. Can anyone tell me how to do this? I plan on putting VCT on the floor after it is finished.
