Not sure what the labor charge will come to, but the material was a couple hundred, the powder-coating turned out to run 250 (uhg), I'd guess total with labor around $800. The welder whipped it out in very little time, and next time will be even quicker.
We had found a place in CA that was willing to build a similar rack for around 650/700 but it was being sold unpainted, so the added expense of this one was all in the powder-coating which was really necessary. Plus, there likely would have been significant shipping charges involved to get rack from that shop up in the SF area.
As far as burying it in concrete, unfortunately it was all I could do to convince them that it was necessary to bolt it down. With the amount of changes we go through on campus, they're wary of permanent anything. In the picture the rack isn't even bolted yet, and likely won't be for another week or two while they decide if this is an appropriate place for it to be used. It weighs around 200 lbs though, and would be difficult to walk off with dragging 3 mopeds in tow. You have to realize that even just sitting there with a few bolts holding it down it will be the most secure bike parking on campus, and although we do occasionally have theft problems, it doesn't seem to be huge problem.
