Hi, there is another option called "Portage" which I use. I was in a similar option to you and this was the easy option. Basically it is an employment agency that handles all of your administration and social security costs. You find your clients and they help you write a contract between you and the client. The client then pays the Portage company on a monthly basis when the work is done, they take off a 10% commission, they pay all of the charges patronales and social security costs and give you whats left over. You generally get a net salary of 50% of the original invoiced fee. This option will probably earn you slightly less than if you are working for yourself, however if like me you prefer to spend one day a week working and earning money instead of working out your invoices, calculating tax, working out social security, unemployment and retirement charges this is a relatively simpler option. good luck,
