I wouldn't pay a dime over 200$ if I were you. Check out Silencerco, they have different trusts at different prices based upon your needs. Their most basic one is available for 99$. Additionally, if you plan to edit your trust in the future you need to make sure the service you are selecting will not charge you for changes. Honestly, you don't even need an attorney to set up a trust if you have a sample of one that passed muster and know what you are doing.
