If I were you, I would want to run this past Etsy to make sure what would be considered acceptable.
I am under the impression that linking to another site is not acceptable per the handbook, unless I have misunderstood that part.
From what I saw on one of your listings, I do not see where you are doing drop shipping unless you have already changed that. My understanding is that drop shipping is where your finished product is shipped from elsewhere and not from you directly.
Best of luck!
