You have an unlimited budget. Return Voyager 1 to Earth.

No.  

Voyager 1 is traveling at 17 km/s, which is at least 11 km/s faster than the local solar escape velocity, which you would have to overcome in order to eventually bring the spacecraft back.  The current record for highest delta-v in a single mission is Dawn, which achieved more than 10 km/s.   Remember, we're governed by the laws of physics, and any spacecraft you send to push Voyager will have an extremely obese mass fraction.  Not to mention to achieve that delta-v, Dawn had an order of magnitude more power available (compared to Voyager 1) to activate its NSTAR thrusters.  

Needless to say, it would take centuries for a spacecraft with today's technology to catch up, and then probably in excess of millennia to bring it back, if it was at all physically possible. Just throw Tsiolkovskies equation at rough estimate of a xenon thruster with fuel tank and giant RTG, attach the giant mass of Voyager 1, and you'll get a pretty good figure of just how giant of a spacecraft you would need to get your mass fraction low enough to slow down Voyager 1.  Not physically possible.
