A few more things worth mentioning: BNSF headquarters will be facing retirement of a very large group of baby boomers the next 5 years, so recruiting for high-paying jobs will remain strong this decade.

I've reached out to a lot of recruiters at healthcare staffing agencies on LinkedIn and on their site haven't had much luck over the past year either.

Just a franchisee that has done well, that now recruits others to teach them what I know.Your point is valid.

What do you charge for recruiting new tenants?

Some recruitment systems have started asking for it as an applicant disambiguator to stop different agencies submitting the same candidate but I always give a fake number an this is misuse similar to how the misuse in the US started.  

I don't personally play a lot, but others on my team love it for recruiting and networking because it's not as formal as even sitting for coffee.

I have also seen several people buy a house (40K) and work their tails off gutting and rebuilding the property putting another 60 to 70K (borrowed) in materials while recruiting friends and family for help only to see a 10K return in 1 year.

Today the established brokerages as well as the start ups are spending a lot of money trying to recruit good agents and associate brokers so you'll need some kind of hook.

What if a company gets a company profile section depending on how many colleagues they recruit from their company?

There's some good existing STR funds that may be helpful with inspiration/recruiting practices.
