I want to make sweet and spicy pulled pork nachos, with a Jamaican style. Need help with the sauce

I know, another pulled pork post but bear with me...

I feel pretty comfortable with making the pulled pork (I like to slow cook it,) but I'm having trouble making BBQ sauce with the right flavors I want and my google-fu is failing me.

I literally had a dream where I was eating nachos with pulled pork, and I'd love to recreate it. I'm looking for a good sweet/spicy version with Jamaican flavors.. Like really spicy ;) If anyone could point me in the right direction I'd greatly appreciate it!

thanks :)
