sad you are in a city.
easy to make a stump just disappear. and no not with a bunch of dynamite. (fun :teeth but not for you)
cut to below grade, dig a hole about six inches wider then the stump and a good two feet deep. then drill in a bunch of one inch holes (pending the dia), top and into the sides, pour in some diesel fuel, add one match.
but that is for us country folk. you city boys would get into trouble doing that.
could try spending a week chopping it up. got a chain saw???
so check your phone book under tree removal..
