Min/Max Quantities

Hey there,

Is anyone able to please assist: is there a way to assign a minimum order value to a specific user role. For example I want wholesalers to only be able to complete the checkout process if they have a minimum of $2000 in their cart. All other users are able to purchase without having a minimum order amount.

I know Woothemes has the Min/Max Quantities extension (https://www.woothemes.com/products/minmax-quantities/), but am not sure if it can be applied to a specific user role?

Thank you for your help
