Hi @Elik, welcome to the forum 
At the moment the only thrusters we sell are T200s. We have a larger thruster on the roadmap, but it’s not yet available, and I don’t believe it’s intended to be 2kW.
You may be interested in this thread which includes some estimates for using T200s for diver propulsion, and links to a list of existing dive propulsion vehicles (DPVs).
