Any WP shopping cart (eCommerce) can do all these?

Can any WP Shopping cart eCommerce plug in do all the following things (except the optional ones)? We are looking for solutions for a few WP sites. Thank you for your time! & Look forward to your feedback.

1. sell 2 kinds of products: (A) tangible plastic gift certificates (no price defined upfront, need customers to enter dollar amount), and (B) membership cards (fixed prices) and then the physical, plastic gift cards or membership cards will be shipped out in regular packages / mail.
2. Optional: a field for the customers to enter some personal message is preferred (such as “order instructions or note about this order”), but it is still ok without this feature.
3. Optional: (deleted) NOT needed now.
4. for gift certificate, online customers will enter their own amount (such as $45, $150, etc, whatever amount they want in the gift certificate) and quantity of the certificates with this amount, and then add to cart. In other words, the site needs to accept a price from the screen and apply it to the cart, just like people enter the quantity of a certain item and update the cart. A quick similar example is PayPal donate button allow both fixed amount and undefined (change-able) amount.
5. online customers can also add multiple gift certificates with different amounts to the shopping cart and check out all at once.
6. online customers can add membership cards (fixed prices) to shopping cart and check out with gift certificates (if there is any) all at once.
7. online customers need to “agree to terms and conditions” before check out – this can be a check box and a term and conditions text box or a few links to various terms and conditions pages or pdf files.
8. check out needs to use authorize.net gateway. When customer click check out, they will be asked to enter shipping address and then click “continue check out”, all the shopping cart items are sent to authorize.net and the customer enter their billing info and finish the transaction on authorize.net.
9. the website owner receive the order info with the shipping address and the customers receive order confirmation email.
