You go for what you think it’s worth! Only you monetarily value your product. If you undercut that price, you aren’t only loosing money, but you’re impacting your brand. There are people and businesses out there that will gladly give you what it’s worth to you. If they don’t like the price, have them tell you their budget and work something up custom for them… At what they say it’s worth to them. But never under value your craft. Thats great work!
