HI sorry for the delay , work what can I say
I am from South Africa , so dont know what would be your closest shop .
If you are planing to use BOB Q you are not getting a good machines you are getting one of the best ! , He will also be able to tell you the best con-fig for your needs and unlike most he can back it up with actual test's
to replace all the components with new ones in you head can be done , that is the easy part to make sure all the tolerances , seats etc are 100% that takes time and skill
I would recommend a good workshop cd/book ,

http://www.baumtools.com/search.php I am sure they are in the US an supply most of the special tools
But at the end of this I would still say just take it to someone to get done ,,
