PayPal Connection for subscriptions

Hi,

We’re finally getting close to launching our site. We need to work out how payments are going to happen. This is what we want to do:

Offer 1 Month, 3 Month, 6 Month and 1 Year Subscriptions
All plans come with a 15 day trial period. If you don’t like it, you can cancel before the end of the 15 day trial period.

You can easily create PayPal buttons with this exact formula. Is there anyway we can do this from the Job Board theme?

Is this something that would require custom programming?

Can we just use the PayPal buttons and not use the Job Board Theme Payment system?

Any help here would be appreciated.
