Shopify: theme modification

Hello! I am currently using the Maker theme on shopify.

I'd like to add the following functionality to my individual product pages:
- A thumbnail carousel/slider that show different angles of the product
- Tab descriptions

I'd also like to add the following to my 'all products' page:
- A filter that allows shoppers to sort by type of product.
- Please post the word 'pineapple' in your proposal so I know you've read this.

Happy to accept proposals above my budget, as I am unsure of how much to charge for this.

Cheers
Rehana
