Suggestions / Advice on renting items.

Hi,

I'm working with a client who has a wedding / event planning business. They also rent out 'items' for use at events (including magicians, bands, DJs, food stands, etc). Anyone have any experience in managing this kind of business in Squarespace? I'm assuming it will need to be a third-party integration to manage the items (dates, returns, etc), so happy to pointed in the right direction or if anyone has done something similar with SS without external help, I'd love to know. Ideally linked with Scheduling to know when things are booked (or not), etc. Any help would be appreciated. Thanks in advance.
