Which business structure for income from different sources?

I have just dissolved my sarl and now need to register in order to be paid for services rendered. We have several different sources of income, and I’m not sure which regime to register under. Currently my expenses are not high, so I’m thinking perhaps auto-entrepreneur, but not sure if I qualify.

Our principle income under the sarl was property search services (my main job) for foreigners and follow-up services (my husband’s, sourcing builders etc. and helping to manage the renovation projects for the property buyers). My contract was terminated last year quite suddenly and without any warning making the necessity for a sarl redundant. However, I still have some property clients and have just completed a property sale (via an immobilier) with one of them.

I also continue in a very small way with the voice-over work I’ve always done from my home studio, and in future also intend to run an occasional market stall, selling off my collections of antiques, paintings and antique clothing. So am I artisan, profession liberale or what? I was registered with RSI although they’ve still not sent me a carte vitale, but will I now have to reregister with them or with URSSAF?
