How much does it cost my will n living will is not going to be over 2 sentences very simple and short

I've included a link below to the Allegheny County Bar Association's DIY Living Will kit.  I would recommend that you retain an attorney to prepare a will for you or purchase a membership with LegalShield (a will comes with your membership).  You should estimate $150-$300 to have a will prepared by a private attorney. https://www.acba.org/portals/1/pdf/LivingWillPowerofAttorney.pdf
