Find out which jobs or products actually make you money

Help me work out which of my products or jobs really make money.

My business: [what you do]
Products or job types: [for each: name, price, materials, time it takes, and how many I sold last month]
What my time costs: [hourly figure, including what I pay myself]
Fees per sale: [e.g. card fees, marketplace fees, delivery]

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

Then:
1. A table for each line: price, total cost, profit per sale, margin %, profit per hour, profit last month.
2. Ranked from best to worst profit per hour.
3. The surprises in plain words.
4. Three actions: push, reprice or drop, with the reasons.
5. A Google Sheets layout with formulas so I can add new lines.

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

If I've uploaded a file, analyse it directly for the margin table and show your working.
