Condensing unit for GSHP Model

Hello, this is my first post here, I'm not sure if this is in the right place, but here goes:

I'm a university student in M.E. and was proposed to design a ground source heat pump to run simulation tests on the effect of ground water change vs. COP of the heat pump.

The water (ground) temperature is going to be regulated by a temperature control unit mated to the evaporator of the system.
The system is going to be run indoors so ambient temperatures should be around 20-25C. I chose my condensing/evaporating temperature to be 35/0C, working fluid will be R-134a .

Now I'm looking for a condensing unit that would ideally have the compressor (~400-500W) and the condenser (air) together with all the piping components. Are these units available anywhere?

Thanks for your insight on this and Id appreciate any input.
