If they are able to deliver with quality, this fee structure would help me improve the cash flow situation in my portfolio. 

You can hand deliver.

The property is just the temporary resting place for your assets until they reach a value where they are more useful/valuable moving forward...instead of sitting on its arse doing nothing.2 - Your cash is not a noun...it's a verb. 

The city eventually hand delivered a letter to him that he needs to tie his trash bags.

I liked the convenience of going to these stores because I could also buy other stuff I needed (and Sherwin Williams would deliver to the job site!) 

The strategy you use is based on which one, when applied to the market you invest in, will deliver the financial requirements needed at the specific timeline you are at in your plan.4 - Budget is what you need to reach in order to execute the steps in your plan, at the each timeline in your plan. 

You can also hire it out, but there is a good chance they will not actually get delivered.  

Easy way around this with a new vendor is that you directly pay and schedule deliver of materials to the job site, not give the money to the vendor up front.If you follow the above the risk and probability of a vendor stealing from you goes close to zero percent.

Thats probably because most of their cash was spent on cigarettes, delivered pizza, and other fast food cartons I see in their trash bins.Unreal!

Also be prepared for the following:  When you win a bid you're EMD usually has to be delivered in 24 to 48 hours & it's non-refundable if you're an investor.
