Turn your day rate into project prices without underquoting

Help me turn my day rate into fixed project prices.

What I do: [e.g. web design, copywriting, bookkeeping, photography]
My day rate: [amount]
A typical project: [describe it]
How long it really takes, including admin and changes: [days]
What usually goes over: [e.g. extra revisions, slow feedback]
What clients ask for most: [list]

Ask me up to 3 short questions first. Wait for my answers.

Then:
1. Work out a realistic project price from my day rate, with a buffer for overrun.
2. Suggest 2 or 3 packages, such as basic, standard and full, with what's included and excluded in each.
3. A clear line on extras: how they're charged.
4. Wording for a quote that explains the packages simply.
5. A check: what my day rate effectively becomes if the project runs 25% over.
