Sheeps, the Institute have a contact here in the UK. If its the "movement" course you are interested in, (Delacato Method) they bring their people over here once or twice a year. Cost obviously much less, i think its £400.00 for 3 days. See if you can get funding from the Caudwell Trust.
If its the Delacato Method you are interested in, can i suggest you do some reading on it. There isnt much if any peer reviewed research on the method. Anecdotal evidence from parents is kind of slim but the detractors from the method and even some of the parents, say that it is very VERY difficult to carry out, and hard on the family and absolutely no proof that any of it "works", that progress may simply be chalked up to the child's "maturation".
I am telling you this because i got kind of excited about it too, until i started to talking to other people and really investigating the "philosophy" behind the insititue (which is connected, albeit, loosely to the philosophies of Ron Hubbard, Church of Scientology, new age stuffy.
That aside, if you can find out exactly what you will have to do with your child via their methods, you will have a better understanding rather believing what you see on their website. Bibic was associated with these people but they broke away to start their own organisation. If you ask them, they will tell you.
Just please be careful. The amount of work and energy that u will be required to do the exercises and work with your child, via their courses etc, may not be something your family can handle. It is extremely intensive, to the point of manic.
But if thats what you want to do, here is the link for the guy in the UK who brings these people over. He is very hyped up on it and will tell you what you want to hear of course.

P.S. not just talking out of my hat, here. I have read a lot of their books and have talked at length with the contact in the UK, as well as with Bibic about this.
