My brother is co-owner of the Silverton Midas in Pretoria and is keen to help out, if anyone on the forum is interested.
He is willing to supply oil, spark plugs, filters, filter oil, Q20 or any other consumables on account - consignment - to someone who is willing to keep at an airfield to use/sell to flying mates. It will be at a good discount.
There is not really lotsa money to be made, more of a service, depending if you rip your mates off

and savings for yourself.
He will also give good discount to forum members buying from Silverton Midas. He is a keen enthusiast on anything technical, so if he doesn't have it, he will find it - except 582 cranks.
Some useless info on the oil.
One of the reasons Castrol and Shell battle to supply oil, is because of the supplier - guess who

of the plastic containers not delivering containers. Oil companies currently sit with a serious backlog.
Shelve price for Shell Nautilus 2 stroke 5l - R 132.00 - Castrol super outboard 2 stroke 5l - R 225.00 - same spec
