How to set up 2 different payment options?

Hi, I'd like to have 2 different subscription types: 1) A monthly plan, where the member would have to manually pay for and continue the membership monthly. $30 per month. 2) A 6 month plan, where the member signs up once, and every month gets charged automatically (automatic renewal). $25 per month.

How do I set up both options?

(Also, on the subscription page it automatically creates a line: "You will pay etc etc." How do I remove this line)?

Thank you! Much appreciated as this is an imperative part of the site.
