Win business clients on LinkedIn without cringe posts

Help me win business clients on LinkedIn without sounding boastful.

What I do: [e.g. commercial cleaning, bookkeeping, IT support for small firms]
Who buys from me: [job titles and types of business]
Problems I've solved for clients (anonymised): [2 to 4 examples]
Questions clients often ask me: [list]
What I can't share: [e.g. client names, figures]
Time I can give LinkedIn each week: [e.g. 30 minutes]

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

Then:
1. Write 4 posts, each built on one real problem: what was going wrong, what we did, what changed, and a takeaway another business owner could use. Under 200 words each.
2. Give each post a first line that makes my buyer stop scrolling, without clickbait.
3. Suggest a weekly routine that fits my time, including commenting on others' posts.
4. Rewrite my profile headline so a buyer knows in one line what I do and for whom.
