yep...id do both. Combine whatever equipment you and your dad have if possible, and run with that. It might not be the best set up, but you can raise cash in the meantime to purchase the equipment you will need. As you work those properties you will learn what your next purchase will need to be instead of having to guess. Also, but keeping both areas I agree with the others about picking up customers in between the two areas.
its a great opportunity in my opinion.
