To much of a hassel. I was going to put a bid in for some in the Twin Cities! but they want before and after pictures taken at every site, only mowed 1 a month,... this would be for about 35 towers @ 45 a piece. Thats only $1575 for alot of dive time and BS.
$1600 isn't enough for you? if you're not already in the area the towers are in it'd give you a foot in the door to expand into their areas. its another $90/day (2 a day) in revenue. The other option is you could save them for rainy days when you can't rut up residential/commercial lawns.
Buy a digital camera ($100) and snap a picture, download to computer. its pretty simple.
All of the towers my company (the cell compnay I work for) are done by one guy (about 300 towers) here in michigan. This guy has been doing it forever. He gets about 3-4 cuts in each year I think. Just when us techs think our sites are being over run with grass/weeds....he gets back around to it. The pictures thing is really silly and a waste a time. If our sites aren't plowed in the winter and cut in the summer, we call the boss and he proceeds to make calls. Sometimes he does have us double check to make sure things are done though. I have talked to this guy before and that is pretty much what he does all summer. Travel, mow, hotel, mow, travel....you get the idea.
