Cohabitation agreement

I am looking for an experienced professional to help craft a fair and legally sound Cohabitation agreement that takes into account my current situation and concerns. I am not sure if I have existing assets to cover in the agreement, or if there are particular legal elements I want to include, so it is important that the chosen freelancer can provide sound advice on what could be included in the agreement. My intention is to ensure that the agreement is fair and legally binding so that both parties involved can feel confident and secure in their partnership. Thank you for your help.
