Auto-entrepreneur plus second business or non profit association: how to get started?

I would like to start a business in Paris. It is a play and learning class for moms and little children. I’ve emailed the flyer to you. The program is designed to improve both physical and mental capabilities and make learning easier.

• How do I register it? Should I register it? Or is just an Anglo-phone playgroup?
• Should it be an association instead of a profit business?
• How long does all of this take? I want to start renting a space mid-September..too optimistic?

Here is my current situation: I am an auto-entrepreneur, Aid to School Learning. I used to be an AVS (school aid for a child with special needs), from September i will work as a pedagogical consultant for a private school in Paris. I would like to keep this part-time, flexible job while I establish my business.

• Is that possible?
• Do I need to change my AE description? Does it matter?
• Is keeping this status a good idea? Doing both simultaneously?
• How would this affect my taxes and my yearly limit?
• What is the tax percentage for associations compared to other options?
• What do I need?
• What are the steps involved? How long does it take? How much can you help with this, as this is a huge stress for me?
• How do I find out the costs involved?
• Insurance? Do I need to have insurance in case a child gets hurt? Or Disclaimers on the enrollment forms?
• An accountant?

Other questions:

• Advice or Rules about subletting space?
• Many people have asked to join me, when do you take on partners? And is it actually a good idea? At the beginning.. if you’re carrying all the costs..
• What else do I need to know about extra/hidden costs?
