It might be worth mentioning how much money you are willing to spend on it,
as it may give people ideas about what could possibly be done yourself, and
what is just not going to be practical.

You may well find getting liquid helium impossible. Here in the UK it is
very difficult to get chemicals dangerous chemical if you are not on an
industrial site. I very much doubt British Oxygen Company (BOC) would
delivery liquid helium to my house.


Stage 1 would be to see what you would need in order to get the He
delivered. Without that you are not going to get anywhere, and I doubt you
will get that delivered unless you have vessels that have been properly
maintained.

I would imagine that just getting the stuff delivered would be next to
impossible without spending a lot of money, especially in the USA.
