You could try calling Big Apple Pizza in Fort Pierce florida and try to get in touch with him that way. Frame it that you want to talk to him about a donation to his charity but have been unable to contact him, then once you get a hold of him, explain what the actual donation is.

If you try to go through his employees by saying you want to redo his website, they'd probably be less susceptible.

Just a thought - good luck, that's a rather noble endeavor of yours.
