Not sure how much change you're looking for, but if your items are in the same category, then using file exchange is second-to-none when it comes to listing quickly.
Another alternative is, if the items are in the same category, to "sell similar" each time
If you have several different categories, then try to group your items together so that you photograph them, and then list them in the same categories.
If all of your items are ending up in different categories, start by doing a search for the item youre selling, then filtering on your ipad by sold listings, then click the item like yours, and click sell similar. Thats the quickest way for entirely unique items in different categories.
Copy and paste descriptions when possible.
Let me know if you have any other questions.
