Have you considered trying to locate a Canadian cryonicist that has already had similar legal documents drafted? Perhaps the relevant cryo providers would be happy to ask around for a Canadian volunteer who already has such an agreement to discuss this with you. After all, being able to obtain this agreement is a prerequisite for you to become a customer, and so it is in the cryo provider's best interest to assist. Once the person is found, you could either ask whether you can use a copy of their agreement, or if it belongs to the lawyers, you could ask the lawyers to give you a better deal since they already drafted one of these and can make changes to the existing copy.
Also, if you choose to lead the construction of a public domain contract for this, then stating that this is your intention may draw more interested people to pool money, and would also result in making a much bigger difference to the world when you overcome this obstacle. You might also find additional resources this way like lawyers who have experience with these.
I don't know enough about law to tell you whether it's likely to be useful to consult an IP lawyer to ask whether a contract, once bought, can be placed into the public domain, but I know enough about human nature to know that if lawyers have a way to prevent their contracts from being released into the public domain, they will want to use it.
Or you could make temporary arrangements like the Alcor website recommends. They say not to delay because you might find yourself in a situation where it's too late. If you get something adequate set up now, you can improve the setup and make it ideal later.
I have just received a message from my lawyer, regarding the preparations of my cryo-based will, power of attorney, and related papers. The most significant quote reads as follows:
Due to the complex nature of your wishes and the undeveloped area of the law surrounding cryogenics and the transportation of a human body out of the country, your file has required and will require further extensive time and research to prepare and draft the necessary documents to ensure that your wishes are correctly stated and that they will be carried out upon your death. As such, in order to complete any further work on your behalf we will require a retainer from you in the amount of $2,500.00. Please contact our office to arrange the payment of the retainer. This can be paid by cheque, cash, credit or debit. Upon receipt of this retainer we will proceed to draft the documents in a manner that best ensures that your wishes regarding cryogenics are carried out.
This is somewhat more than I was hoping, and expecting, to pay. While I do have a line of credit which I can use to pay the immediate cost, I do not have sufficient income to pay off that cost any time soon, and I am thus debating whether or not to pay it.
One option that occurs to me is that if my law-firm is able to nail down a set of documents to maximize the odds of a Canadian cryonicist's will being properly carried out, then that would be to the benefit of a number of cryonicists, here and otherwise; perhaps even enough so that it could be in the interests of cryonicists here to help cover the legal fees, instead of having to hire new lawyers to separately re-develop the same paperwork. (It would be reasonably trivial for me to provide proof of my lawyer's existence and the retainer request.)
I'm also open to any other ideas that anyone here could suggest.
