I can get stuff at discount if you're seriously interested. Or you can buy the parts used on pinkbike.com i could help you find a decent used setup
the hardware comes with the stem when new and most purchases with used they include them.
I can get candycomponets stuff for a good deal they have stem and bars

If you went used you could get it all for under 100 including bars. As far as the machine shop im not sure what they would charge i used my own mill.
The holes to drill are 50mm x 35mm rectangle 50mm being the width and are a T6 bolt. Dont drill until you get a stem and fit it correctly. Technically you could do it with a drill as theres a little room for slop.
or i can get raceface ( whats on mine)
http://www.raceface.com/ they even have carbon fiber bars if you wanted serious bling
i didnt have my stock pole on and never did so im not sure if you could run a bar with a rise. Mine pictured is 1 1/4 inch but to avoid your pad when turning you might want one with little to no rise. im just not sure on the clearance.
