To purchase Foam filler and necessary tooling to fill foam into fishing boats?

i would like to fill my two boats with foam for extra bouyancy and safety my fishing friends that have boats are also interested,we Live in Botswana (Francistown) and it is difficult to get the boats in and out of the country the permits ,travelling distances etc,so i have thought about purchasing the equipment and manuals and instructions to do the foam filling my self or is it possible for someone to travel to Botswana to do the foam filling,we can get alot of boats together to be filled to make it worth the effort.
