Ok I figured it out, might be sloppy but it works. For the code below, if the customer is a retail customer than the minimum order is what is set in admin. If the customer is a wholesale customer in this case the minimum order is $300. Just replace all instances of 300 (in red) to what you desire. Ideally you can add a field in your database and change the coding instead of having to modify this file. Hope someone finds this helpful.
