If she engages back, I will remind her that we would always be interested in working with them directly if there is anyway that we can help to fill a need for them.

You want to get the process down to that and then repeat it, repeat it several times, even do two at at time when you can. 

I had the luxury of filling the units while still in FL. and am only a month in.

The day after closing on the home I quit my job and got into mortgages (my lender was also a friend from high school and made the process so incredibly simple).

I share my contact info, let them know about the transition in ownership process, how I operate, what they can expect, etc. 

What good is talking about a lower fee if they cannot fill a unit.

If you want an offer fill in the form.

The costs and process will completely different.

Another big factor in my search for an agent is someone who has extensive experience in the process of vetting prospective tenants. 

You may want to talk to an intermediary as they'd have a lot more knowledge on how the whole process works than I would, it's fairly rare that I see something like this happen, but I usually get it once every year or two.
