Database for subscription based website

I have a horse racing tipping site. Every day I send my selections via email (see example attached). This is currently a free service but I want to change to a subscription based service through paypal. Members would have the choice of a daily subscription or monthly subscription. There would need to some kind of database where members register for a 3 day free trial. After the 3 days members would be blocked by something like software defender and be taken to a window where they click on either daily subscription or monthly subscription or exit. If they chose a subscription they are taken to a window or similar and given the option of paypal or neteller. After payment they are given access to the day’s selections. We would link database to current website. Now for my second requirement. Where to and how do I upload selections? Say I am a member and I register. I login but where am I going to? I want to see that days selections. I want to able to copy and paste them. The selections include the time of the race, the course, horse name and whether the selection is a back or lay bet. So each day I would simply like to login to the data base and cut and paste selections (see attached) Any idea’s or thoughts on how we could tackle this please PM
