Default Taxi calculator? (propeller type and speed, aircraft weight, taxi speed)

Is there such a calculation/formula? How can you tell what
propeller to use, how fast it should rotate, and how much weight
it can push along the ground?

Specifically... I would like to tell what sort and size of
propeller rotating at what speed, in calm air to push 100 or 200
pounds on smooth and level pavement with zero rolling resistance
to about 20 mph.

Thanks.
