King,
Can you give us a little more info...how long out of residency, past practice experience, general location, rural/suburban, east/west, etc. While I havent used practice fusion and only w/ ac, i started 2 y ago with wife doing billing. Ac's weakness is it has no practice management, but it will in 6-12 months i believe. We've hung in there with a partially electronic/partially paper (day sheet on legal pad!) system and with a smart motivated biller (aka my wife), our AR rivals anyone out there. There are a lot of resources and opinions out there for individuals in your position and yes, you can be successful. But it is hard and far from guaranteed. Choosing your emr is only one piece ( a large piece) of your puzzle.
