You won't be able to put your revocable living trust and pourover will (what works for most people) (look pourover will up online, it's important, your lawyer will do it for you) together yourself online.
Look for an estate lawyer in your area. Look online so you know what questions to ask to find a good experienced lawyer. Most of the lawyers will offer a free consultation so you go talk to them and pick one.
Keep in mind that you are the one who will have to come up with all the answers to the questions to put your estate plan together. The lawyer can't fill in the blanks for you. But the lawyer will give you the questions to answer.
The experienced estate lawyer will put together your estate plan. Ask if the lawyer will charge when changes or questions come up. They will come up.
If your trust is ever challenged, you don't want you heirs to go in front of a judge with a do-it-yourself trust. The judge will be much more impressed with a trust put together by a lawyer.
Somewhere around $2000 and up depending on complexity seems to be what most pay.
