New lease purchase...Corporation help

Looking for input on forming a new corporation with the sole purpose of purchase existing production leases.

Curious on what type Corp(S or C)? Could this be done with LegalZoom (online service) vs a $400hr attorney? Also curious about expense costs vs capital costs and where existing tanks, rods, casing, pump jacks etc would be factored into the yr 1 calculations. Obviously looking to maximize year 1 with expenses costs(losses) rather than capital/depletion costs that need to be amortized.
