I don't have a recommendation for a PM but would recommend asking a lot of questions of any companies you vet regarding their tolerance, process and appetite for Section 8. Here, there are a lot of PM companies who will manage Section 8 properties and almost none of them do it well.
Asking them some basic questions will help you determine if they know what they're doing:
-What percentage of their properties are Section 8 and/or how many Section 8 properties do they have?
-What specific processes do they have in place for Section 8 (it has additional paperwork and rules)
-What is their average turn time between 2 Section 8 tenants
-How & when do they request rent increases with the PHAs
-How do they keep the rent ledgers for Section 8 tenants? (They should keep 2 separate ledgers - one for the tenant and one for Section 8 - otherwise, the ledger is a mess and it gets difficult to tell who owes what)
-How long is it typically between when they place a Section 8 tenant and when the rent starts to come in (Here, it should only take 2 to 4 weeks)
-How does the screening process change when screening a Section 8 tenant? (They may/probably should have something different in place around Income/Source of Income to pay rent/income multiples)
If they can't quickly & clearly answer these questions, I wouldn't recommend going with them. Section 8 is amazing when done right but it is quite different than market tenants in a lot of ways and PMs without the knowledge and experience will cost you.
