Charge based on the value given to your customer. If your small set of features offers value, talk to them about what that value is. Don't guess - actually ask your early adopters what they feel is fair. After all, you'll need to be in close communication with them anyway to be sure the product matches their needs, which means you'll need an open and trusting relationship, so include price in those discussions.
