u can even ask a retired lawyer friend(if u have one) to do it for you
some retired lawyer do this as side business

the whole thing about will is that is only makes the process a little easier and faster, it doesn't really change much of the process and it's fees at the end

think about it
no firm can grow so big by doing 1 business...no lawyer firms ever rely or just offer doing wills as their service
no funeral parlour ever grow big by doing funeral service alone....nirvana got so big because they're a real estate company, not a funeral parlour
