Adding an art commission option to my store

[Allyjane1]

I’m a digital artist, and I sell several different art products through my Shopify store. However, my bread and butter comes in the form of art commissions (specifically portraits). Up until now, I’ve been obtaining my commissions via social media. However, I’d like to combine this aspect of my business into my Shopify store.
What is the best and easiest way to offer a commission option on my website/store?  I’d love for the customer to be able to purchase the digital commission on a canvas from my website so that the process will be more streamlined instead of them receiving a digital file and then having to figure out how and where to get it printed. That process confuses older customers. Any tips or ideas are welcome!  I’m a newbie, so when offering tips, the most basic breakdowns of the steps involved are most welcome!

Thank you for your suggestion, but I see that this particular app has a
monthly fee of $24/month. I’m trying to avoid any additional fees, if
possible.
