Ok there is a company that can repair the blades in lower 48th. As it stands with delamination on the trailing edge the aircraft is not airworthy.
Maximum weight is 2150 lbs. You might want to do some calculations about weight before you start thinking about external loads. I can't see you having enough useful load to make it worth while.
The F28A does not have a lot of excess power and the throttle is not correlated.
Good luck.
