I have a rush delivery service which I offer as a separate listing. My normal turn around time is 1-2 weeks, plus first class shipping. But sometimes people need something way faster, so the rush listing ($7) bumps your order to the top of my list and includes Priority shipping, there's a separate one for Overnight.
I wrap everything in white tissue, ribbon and a sticker with my business name. I don't think that's really what people want to put under the tree this time of year. I used to have a $5 gift wrapping upgrade, but I haven't kept it current as it wasn't that popular and there are some things that are weird sizes and shapes that wouldn't work for that type of wrapping.
