App to add more variants plus a request a quote and lead time option

[s4]

I have a client that's going to be drop-shipping products from another site and everything is pretty much a custom quote. They would prefer not to show pricing on their site and instead have clients request a quote and lead time.

Here are the features that we'd be looking for. It can be more than 1 app.

• 5 minimum and up to 15 variants if possible
• Add to wishlist
• Compare Products
• Suggest discontinued items/replacement items
  Read more
  Call for a quote and lead time
  Item on backorder, notify when back in stock

As many of these that are possible is what they'd be looking for.

This is what we are trying to replicate, something similar to this: https://washroominc.com/product-category/bobrick-washroom-equipment/koala-kare-baby-changing-station...

uggestions appreciated. Please let me know which features the app has if possible. Thanks!
