I would recommend a machine shop with CNC machinery.
Drill press probably not viable, you may spend more money redoing it several times.

Short answer no.

Long answer possibly. Drill bits don't make round holes. With these tolerances you will need to ream them. Drill 1/64th under size then without moving the part, install reamer and ream hole. Then change to drill bit, move to next hole and repeat. It might be able to be done but it will not be fun.
