It is next to impossible to provide an accurate quote from your drawings, are all the holes, pockets and slots countersunk? I am sure plenty of the desperate fools in here will quote off of what you have provided. But someone like me will need a lot more information, like tolerances for starters. Also since cost is probably an issue, can you live with bowed surfaces. Any unmachined surface
will probably be bowed up to .002 per inch, if you want them flat the part will need to be machined from 1/2" plate and both faces fly-cut. Why don't you just post the dxf files? You should probably list your location, shipping time can eat up a bunch of that 2 weeks if someone is too far away from you.
