Hello Paul, my name is***** am a solicitor and I am happy to assist you with your question today.
1. If this is a business to business arrangement there is no legal requirement for a cooling off period.
2. Yes a member can be charged from day one.
3. This may be something that can be offered as a premium service as it is a core business document and cannot form general advice. I will make an offer separately for this.
If you have any further questions please do ask. If I have answered your question I would be grateful if you would take the time to rate my answer, thank you and all the best.
