Ah no, MOB. Let them write their own wills. I make far more money as a solicitor fixing the problems with the crap wills later than I do making your standard will.
I'm reminded of a time when a local ladies club asked me to do and witness a generic will for all their members at, I think, a rate of E30 for each will. Most were in their late 50s/60s, some married, some single, some widowed, some separated - each would need to be separately advised and their individual circumstances analysed. I declined.
