Hi Sean -
Endorsement issues can always get a bit hairy, and your's is a particularly tough case since you've been working in the field so long. The trouble is, licensure by endorsement is set up in just about every state that has it, to allow credentialed MTs to come in and get a license in the new state, so long as the requirements in the old state compared to the new state are roughly equivalent. Your original state, TX, for a long time required the lowest number of hours than any other state in the country, and now you're moving to a state with the highest number of hours required in the country.
It's admirable that you are willing to step up and play by their rules to get the hours you need, and I certainly understand your need to work in the transition. Would it be feasible to stay in CA, keep working under your CA credential and get those hours before you move? That way you could keep working while you're in school... You'll want to be careful about the hours you do as well - what I know of NY is they have not only a high number of hours required (1000), but a very specific breakdown of what those hours need to include, so before you pick a school to go to, make sure the time, effort and money you put in will actually get you the specific requirements you're needing.
It sticks in my mind that NY used to have an option for endorsement for MTs with 500 hours as well, if they also have other training or education, even if unrelated to Massage Therapy, but that may have changed. Something to ask about, if you have completed any college hours or other trainings. Along those lines, you also could call the NY folks and find out if the CE credits you have taken over the past 11 years might count in your favor.
Also, some states also have a "temporary permit" or "limited use" option that you could ask them about. (I think in most states that is for applicants who are just waiting for their application to be processed, so they can start working, but it's worth a shot.)
Just some ideas - Hope it helps.
