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.  

We're selling a property to have our seed money, and working with an agent that initially seems to be very well connected, professional, and can deliver.

If that doesn't work, deliver it by hand or tape to their door as evidence of delivery. 

Who is fairly priced and who can deliver 

Do you deliver a pay or quit notice when you can because of how late she is.
