@Vensetra The current version of the Custom Listing form is all but unusable. I suggest you just create a normal listing with the bare minimum information, publish and pay 20 cents, then send the link to the customer.
It's just not worth the frustration - and there have been many posts that sometimes the Buyers aren't even to open the links that Etsy sends! Ridiculous, isn't it?
* I just created one such Custom order in my shop - you can see how I left off lots of the info. like the tags and attributes.
