There's no 220V to be had, so it's that or nothing. I'm not expecting 70 deg, but knocking the edge off of a 100 deg day would be nice. These units also offer heat, which would be a bonus as well.

I use two 9,000 BTU units in a 25'x12'x12' plastic fabric garage at the office. This is installed inside the warehouse, so that it can be airconditioned. It will knock the temp down by only 10-12 degrees. YMMV, since I have only heavy plastic sheet as my "wall" with no insulation. I've considered installing a 3 ton "package" unit.
The portable units use the inside to cool the coil and then send it outside. So, you will get a constant small flow from the outside.
You can find 12,000 BTU mini-split units which are 110VAC. Installation is pretty simple, you can find how-to on You-Tube. You will need a vacuum pump.
