Build a staff rota that adds up hours and shows the gaps

Help me build a staff rota.

My business: [café, shop, salon]
Opening hours: [days and times]
Cover needed: [e.g. 2 people weekdays, 3 on Saturdays]
Staff: [for each: name, contracted hours, availability, skills such as can open up]
Rules: [e.g. no one works more than 5 days in a row]

First ask me up to 4 short questions. Wait for my answers.

Then:
1. A draft rota for next week as a table: days across, shifts down.
2. Gaps and clashes highlighted, with suggestions.
3. A reusable Google Sheets layout: hours per shift, weekly total per person, and a cover check per day, with the formulas.
4. A simple shift-swap rule staff can follow.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or figures. UK English.
