Hi Mike,
Another possibility...

I don't know whether this alternative is economically competitive, but since Obsession can't build around your optics, here is another builder:
Teeter's Telescopes (USA) will build a custom telescope around your mirror. The build quality in my experience is excellent; shipping and duties would be the important consideration. I know that Rob Teeter has shipped to Asia, so he has experience with international shipping. It might be worth an inquiry.
I own a 14.5 inch f/4.5 built by Teeter. I considered Obsession but chose Teeter because he could customize to my specification. I talked to him in person before ordering and he answered all of my questions thoroughly and competently.
This telescope was reviewed by me in Astronomy Technology Today:
http://www.teeterstelescopes.com/att33_teeters.pdf and describes my 'acceptance test'.
By the way, I owned a 20 inch f/5 Galaxy mirror made in 1989, and it was an exquisite mirror. If your 18 is as good, I really hope you are able to use it again.
Good luck in your quest!
