WhatsApp Lead Gen for UK Dealers

I run a UK business providing affordable websites for independent car dealers.
I am looking for a reliable freelancer to contact selected UK car dealers by WhatsApp using a short message that I will provide.
The work will involve:
- Finding suitable independent car dealers from sources I provide
- Checking the business details
- Sending a short WhatsApp introduction
- Not repeatedly messaging people who are not interested
This is targeted B2B outreach, not mass automated spam.
I will provide the message, website links and instructions.
Please tell me:
- Whether you have experience with WhatsApp outreach
- How many businesses you can contact per day
- How you avoid WhatsApp account restrictions
- Your price for contacting 100 / 500 / 1,000 businesses

Do not use automated bulk messaging software or scraped personal numbers without my approval.
