Interestingly, there is a company called Skyacht that is/was building a “Personal Blimp” that retails for around $200,000 and runs on hot air instead of helium. Perhaps you would be interested in their email list?
However, they may be like the Aetherlight or out of business. Max speed for this thing is about 10 miles an hour, so it would need to be modified.
(Typical blimps cost $2 million to purchase and $500,000 to operate.)
