went out to bid a self storage company today, and got to thinking. they are charging $165.00 for a 10x30 room, no utilites. not a terrible price i thought. i bid the place at about $85.00. was considering adding the option to the quote of renting me the 10x30 room for no charge. i would in turn mow it for no charge and would include the rooms rent over winter in the quote, since i would be making an extra $85.00 if they accepted the cash quote, sound like a good idea or is it unprofesional?
