An example of a user-friendly web interface for an online photo and souvenir printing service?

Question

User interface

Has anyone met (seen) a convenient web interface on the site for selecting photos for printing and a souvenir?
Well, something like:
1) I upload my photos
2) I choose for each size and quantity (pcs)
3) I choose a photo for printing on souvenirs + quantity (pcs)
I looked at all sorts of netprint and the first 2 pages of search results in Google - interfaces are just unrealistic old crap...
Can you tell me something?

Answer 1

So far I have settled on this interface:
order window:
adding a photo to the order:
adding a souvenir to the order:
not wow, but I don’t know what else to think of and where to peep ...
