Update purchased php event calendar

We purchased PHPJabbers ([login to view URL]) event calendar but we require some additional features added to the script; as a non profit charity our budget is very low so we're hoping someone can help us out for a small fee. We did speak to the company but their fee was so expensive we just can't afford it. Their script is very stable and works great but we require the following additions. 1. Ability to add an image to the event 2. Additional input box for further information 3. Booking section to be placed on a separate page 4. Automatic scroll system placed on our home page that displays events 5. Search system for our events. I've attached some images to try and show you what we're looking for. Any questions please ask.
