Would there be a way for me to order a longboard blank made with reverse rocker from you guys so I can shape a noserider?

You could use another longboard blank and 'flip" it so the nose rocker would be used for the tail (as long as your outline template fits in the nose area [which would be the tail of the blank when you flip it]) Some guys flip the US Blanks 98Y for nose rider designs.

Or we can custom order you a blank to whatever rocker you want. No problem.
