No sorry while I'm unsure about the machine crudentials and some aspects of the build 5K is not over the top really when have to take into consideration this is a business and he has to provide warranty and all that goes with running a business. Your 2K only reflects a small part and large cost of building these machines comes from labour and running costs.
Obviously the man is looking at buying so building isn't his first choice or a choice at all.

Also don't get why you say needs wider rails because width doesn't really come into it provided they are suitable for the job and mounted correctly, it's the load ratings that matter and these are well on top of the job in all ways. (Thou would possibly have used flanged bearings on X axis.!)
