Would be nice to be able to set a lead time requirement for certain services so they could only be booked out more than X days ahead.

Example: custom color requires us to phone consult with client for color and also where they are coming from, then order said colors and wait for delivery. So at current we either have the option of having it bookable online and then calling and rescheduling if we need more time to order or we don't have it available for online booking all together.
