I would suggest trying Kate Wolf and see if she knows anyone who
would carve the angels...look up her sight: Kate Wolf Designs.
I did write to the poster offering to carve the angels and asking a
few questions. I.e. dimensions, time estimates, deadlines etc. I
included my web site, and attached a photo of one of my fossil
carvings. I did not receive a reply of any kind.  perhaps they
found someone or changed their mind.
