HI there,
you seem to have prepared everything :)
I can do the card by hand, in pen and ink and watercolours, so it can be handdrawn instead of "handdrawn". I would then use the scan to complete the card design. Or, if you prefer, I can do the entire piece by hand and send you the original (if you are willing to cover the postal expenses).
Some of my recent work is available in the portfolio section at https://www.freelancer.com/u/ddimitrovska.html. Let me know if you are interested.
Hope to hear from you soon,
best,
Dusica
