I've got a roll-off dumpster arriving Friday to assist in cleaning things out. 

Only a very new Realtor would be willing to do that.If you want a top quality Realtor to work with you, my recommendation is a) find one at a REIA/real estate investment group and b) when those weekly or monthly search updates arrive, do as much as possible research beforehand to make sure it's worth wasting their time. 

e.g. send X message 5 days before they arrive, send Z message 2 days before they arrive, etc.
