How much you would charge for template customization and how to get paid?

Hello,

A customer asked whether I can customize one of my templates for him, and requested a quote.
Since I’m new to VH and never done customization service before, I have 2 questions.

  1. I know it is hard to tell a price. It may differ from template to template. But, can you tell me an average price for customization? (Let’s say it may take about 3 - 5 hours)

  2. If you do the customization, how you can get paid?
    Because it is not like, a customer purchasing one of your templates. At this point, he is not purchasing any license. So, How do you charge him? (I mean, how do you receive money?)

Appreciate your help :blush:
Have a good day!
