Build an Online Store

I need to set up a PayPal shopping cart to sell tickets, integrated into a simple, HTML5 (Adobe Muse) website. A VERY simple version of AirBNB (but with dinners instead of homes) with minimal functionality. User journeys: HOST A host registers on the site to capture basic contact information, description of the event they are hosting, and add a few other parameters describing their event. This will set up a personal page which they can log in to, edit, upload photos, and share via email. If a host sets up an event, this sends an alert to the site administrators. Events are either open or closed. Open events become public pages to the website. Closed events are hidden behind a password. PARTICIPANT (paying) A participant purchases a ticket to an event (see above). If the event if closed, they have to log in with a link shared by the host. If the event is OPEN, they can find it by browsing on the main site. They buy a ticket to the event of their choice via PayPal and this generates a PDF ticket. They can always login and download that ticket. PARTICIPANT (free) Certain users will receive a unique number which they enter once per session to give them access to an event. They may bring one guest. They receive the same link as a paying participant. DONATORS A donator can simply make a donation via PayPal to the site. They receive a standard donation invoice.
