LF help with SPO for project

I am looking for help with a project that requires me to create a landing page on SPO where my team can access and claim a cheque that remains unclaimed on the companies books. Ideally I would have a page that says the amount, cheque date, client name etc. and then another option that perhaps has a separate link to the cheque image, if possible. If not then a “claim me” button would suffice.

If anyone has any templates I could look at? I’ve tried YouTube, Reddit, and googling but I’m not even sure where to start exactly.

TIA!
