hey guys!

I was asked by one of my old highschool teachers to do some repair and installation on an old shipping container that hold's the schools track & field equipment. The conatainer is located at least a good couple hundred feet away from any available power and i don't want to have to bill them for renting a generator. In short, i was wondering if it was possible to power a small 110v welder like a millermatic 135 or lincoln sp135t and a grinder from a small 2500 watt ipower inverter, or do they even make the inverters that big? i'm just brainstorming ideas.. i may just end up renting, couldn't cost that much right?
Just wondering if anyone has any thoughts or expiriences?
Thanks for the help!
