@Joseph SkatesI'm not sure I clearly understand your question.If your business is collecting waste then you will most likely have a couple of possible revenue streams: a dumping fee you may/may not charge to folks who bring the waste two you;scrap fees you may collect on sale of the various component elements you extract from the electronics.Depending on where you are, there may be a provincial program which will supplement one of those revenue streams (kid of like the tyre levies charges my many/most provinces).  

The 2 main components of wholesaling are marketing and having a good buyers list to flip the deal to.  

We have regulated the components so strictly that it's very challenging to acquire them and they usually cost more than the meth you could make would cost.

There is probably a component of landscaping that was done incorrectly around the garage creating a flooding scenario.

Some of the groups cost money to join, because they include a training component, for those with no prior experience.

A lot of times to get an acceptable rent/price ratio these days in this market, you'll be looking at a value add component, welcome to real estate! 

My husband and I have recently purchased our first home and investment property using an FHA backed loan with a 203k rehabilitation loan component.  

How much more can I expect to spend on the other components of finding leads through a website?

I do this for any vendor I use each year, as I carry workmens comp on my properties for myself and workers I know aren't covered themselves. but if I can prove my vendors have insurance when I'm audited, so my insurance agency compute rates in my favor, because vendors had their own coverageAs far as lien waivers, it's good practice to have anyone that worked on the house sign they have been paid and a lien waiver is used for that. 

Another important point for Engineered Certification & Foundations For Manufactured HomesAdding a retrofit doesn't mean the existing components are removed (above).
