Title says you are offering for free so I have the following questions

• Have you been handling clients in Switzerland since 2016 as authorised by the Swiss authorities?
• Do the Swiss recognise the IMDHA body and it certification
• Do you have public liability insurance in Switzerland allowing you to treat people
• If, yes, is this treatment that you are offering for free to complete your advance studies covered under your public liability and are you legally and professionally allowed to offer it
• If, no, are you supervised by someone who has appropriate insurance and recognised Swiss credentials
• If again the answer is no, I don't believe that you should be offering it on this forum as hypnotherapy and regression therapy has the potential to do significant emotional harm

EDIT - according to their website, the IMDHA (International Medical and Dental Hypnotherapy Association) is a referral service and not a qualification in its own right. Perhaps OP can explain her actually qualifications and the amount of study required to get said qualification
