Should be able to find a used bike like this for less than $150, and modify as needed
I'm prolly into it about $600, before the ebike kit ... So that ought to be doable on your end.
If you can do basic bike work, this is probably your best bet. Old hardtial or rigid MTB frames are workhorses ... you can base any kid of bike off them, and haul any kind of load. Most of them are built to take a 200-pound rider dropping six feet onto rock, so a 300-pound rider hopping a curb would be nothing.
But be like @
BrocLuno and get a real fork.
