Better Subscription Mod

[elbeer]

I am looking for someone to modify the current subscriptions in smf with the following features:

1. Add/Remove a 1 day trial which auto upgrade to full paid membership after say 1 hour, or 24 hours
2. Prevent people of certain groups from viewing certain subscriptions e.g. if someone is already a member of group A they can not see the prices for group B
3. Add a feature to sort in an order on the subscription page. e.g. weight the subscriptions
4. Increase the size of the text permitted in the descriptions and titles
5. Add a coupon code to the subscriptions with an expiry date

Is this possible. Are any of the above easily added
