CUSTOMISE BOOKING TIME

I work in real estate. I want to create 5-minute or 10-minute slots for potential buyers and tenants to view properties. I want to set for example every Wednesdays and Fridays ONLY for viewings at a particular property and just send that link to everyone interested in that property. `Is there a step by step guide where I can see how to do that. I am on the $29 lifetime subscription and I bought it for this purpose ONLY.
