He's on facebook and has a website for contact info.

For each property listed through a Section 8 website, over 100 requests for application are received within the first couple of hours.

Do you know of any good websites where I can post my deals?

I'm impressed by your website by the way.

Does anybody know any good websites or services for batch skip tracing commercial property owners information?

With this in mind, doing the market research well is key and I can share with you some tools / websites that i used for my own (for example idealista data or national stats), so you can check in which cities population is growing (just a few), unemployment rates, rent/buying $ per m2, etc.  

Simple things like a branded email at your domain and a website can open a lot of doors. 

And they sell lots of them.My issue with them is that from a quick look it looks like they're selling everything at a 20-30% premium (which I understand and respect).

Due to the nature of the shorter lease terms, I am spending an excessive amount of time updating my Excel spreadsheet, MLS, business website, Airbnb, VRBO, and other platforms.

That being said, you could be the individual who helps identify this respective vendor.
