Which is the best election for...?

Hi to all,

Can somebody help me?

I am to begin the design and the construction of a workshop-made
cutting-milling machine of the following dimensions: 2800 x 2000 x
100 mm (9' x 6.5' x .3'), for wood (MDF), with a precision of, at
least, 0.5 mm (0.02").

I don't have experience in the matter, for what I appeal you so that
suggest me the best alternatives from the point of view of the
relationship cost-benefit in the following aspects:

In other words: That you would use in each one of the aspects of the
machine?

1) Table/bases/supports
2) Lineal movements/joinings
3) Motors
4) Electronic drivers
5) Software
6) Other aspects that consider important

Any advice is very important for me!

Thank you in advance.
