I decided to declare the war on bamboo in my backyard. Going to be a tough one, but I need to start by chopping it all off + clearing other crud that accumulated in the yard. City picks up yard debris but it's just going to be too much of it to unload all at once. So I am thinking of getting a roll-off container. Questions :
1. Is there any sort of rule of thumb to try to figure out optimal or minimal container size for the job. Say if I have X sq ft of standing bamboo, can I convert that into size?
2. When I start calling places, are there suggestions on how to pick one over another? Price of course, but I am sure that's not the only thing. What else?

Thx!
