I would do it through some agency if it's only part time (to get you through until PP volume picks up or whatever). Yes, that neuters % kept, but it's not worth it to set up equip, vehicle, marketing, staff, billing for mobile if your main goal is something else. Work for one of the big ones, work for a mustache, or just buy some old retiring guy's work for a reasonable price.
Whatever you want to do, DO IT. Asap.
Save the$ up, start in the role, make the contacts.
...If you want to be an office pod, do it.
...Hospital limb/pus/wound guy? Do it.
...Big recon? Find that role.
...Prefer mobile? Go get it.
...Teach or publish? Good friggin luck, lol.
...Admin/owner/boss? Start making bank and biz contacts... or climbing hospital politics ladder.
Not many start in dream role, but track that way... ie, PP associate to savings to PP owner... or VA lackey to pass ABFAS to real hospital recon guy.
I see no point to picking EMR and setup for nursing home if that's only a bridge plan to keep finances afloat. Plan the true goals and take a lower % on the mobile to not distract from the end game you want. I did the crap mobile work to bridge non-compete gap years ago or supplement income, but it's a total waste of time to admin it if it's only a temp plan. You're better off searching and planning for what you actually want. It's demoralizing to put significant effort into a 'side hustle' you dont enjoy. Jmo.
If mobile is the only type of podiatry you plan to do (definitely seems to be "NO" here), then, yes... run it yourself.
