Design Wedding Ring

Where could I engrave a vine on a two tonal wedding ring?
I want my wedding ring to be more festive, but I don’t want to pay hundreds more dollars for some kind of special design. If I could engrave a vine or a trinity knot on my band, I’d be really happy! Anyone have any ideas?
Consult a jeweller that does computer engraving. Hand engraving could look amateurish and ruin the look of the ring. Computer engraving is not that expensive.
