reading this post is how to relive the 'my' history of the passage from 2d to 3d!
practically the same situation: micro family-run company, hand-made designs on greased and bisunti sheets (until the passage to 2d) and when there were no drawings of any kind meant that somewhere there was a template or a template or sample to be copied every time!
I would say that the passage sheet ->2d was well digested at the time, when I arrived in 2002.
the difficulty was to move to 3d, explaining what were the priceless advantages in the face of an entirely acceptable expenditure: I have done more than a year of 'treatment' before I can buy proes.
at the beginning I was titubante and I said: "We don't need proes, we just need a mid-range." in fact for us a mid-range would have been enough, but you want to put

.
to convince me of the choice was the demo 'dedicated', organized in four and four eight, that only 'those' of proe have proposed to me: I highly recommend this road, whatever your choice.
price question: at the end of the negotiations the software package+hardware+pro course had a comparable cost (around 10,000) and in a case less than that of other mid-range, therefore there were no excuses!
ps: we produce machines and the main processing are those of medium carpentry, mechanical machining, sheet and assembly.
This is my experience I hope you need it and good choice!
