Win office and business customers for a consumer business

Help me win regular orders from local businesses.

What I sell: [e.g. cakes, sandwiches, flowers, cleaning]
The businesses nearby: [e.g. offices, estate agents, surgeries]
What I could offer them: [regular delivery, account, invoice]
Minimum order and lead time: [details]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A simple business offer: what, how often, how to order and pay.
2. Who in an office usually decides, and how to find them.
3. A short intro email and a 30-second walk-in script.
4. A sample box or taster idea that's worth the cost.
5. A follow-up message for a week later.
6. A note on email rules: the ICO says you can email companies, but check its guidance for sole traders and partnerships, and always include an easy opt-out.

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