Neither one of us want to pay thousands, if we don't have to.

Unfortunately, there are certain costs (fuel, mandatory inspections
and maintenance, engine ware, hangar/tiedown, insurance, ...)
associated with operating an aircraft, so you would most likely only
trade labor hours. Given the facts that Certified Flight Instructors
currently earn about $30.00/hour, and it takes about 25 hours of
instruction to prepare for the Private Pilot checkride, your savings
would only amount to about $750.00 assuming the patent application
required 25 hours to offset the instruction hours.
