In my Engineer days , I worked for Maint co, they had one of the Mechanics flying around the place( in a Comanchee) picking up Aircraft spare parts usually for AOG aircraft. Go to a 10 aircraft maint company's and offer then your product.........you never know.
I used to fly a 206 from PNG to Oz with a full payload of Crayfish...good bucks in that.
The other one is filling your 206 with Gourmet food from Harrods and flying to the french riveira, so all the trendy french can say they have Harrods food delivered to them fresh from london!
Food for thought!
