Just make sure that the pump and motor are sized appropriately for the HP needed. In this case, 25 HP or so.
Also the pump and motor should have the same displacement to keep similar RPM's on the blower as the PTO. I would guess you are going to need something like a 10 cubic-inch pump to give you up near 20 GPM at 2000 PSI, needing about 30HP from the 540 RPM PTO to run it.
A 1000 RPM PTO can use a smaller pump to get the same flow.
The simple way to go is one of those pumps that slip right on the PTO shaft like a model HC-PTO-1A. I have seen them for about $350 new - could be half of that if you can find a used one.
A 20 or 30 gallon hyd tank is going to be about $100. The 20 or 30 gallons of fluid will not be cheap, either. You might be able to use a smaller tank if you add an oil cooler in the line somewhere, but a coolr with a 12v fan for 20 GPM might cost $189 or so. However, the oil cooler would also make a great cab heater when using it for snowblowing!
The motor will need to b about 10 cubic inch displacement to match the pump to keep the RPM's about the same. Since reversing is not an issue, nor is low-flow or locking performance an issue, you can use a larger variety of motor types - almost any motor with the right displacement and rated for 20 gpm continuos flow at 2000 PSI will work for this application. If a non-reversing type, make sure it spins the desired direction!
I have seen appropriate motors in the $350 range.
