Amazon UK Sellers Lead Generation

Hi,

I run a UK wholesale distribution company and I'm looking for someone who can build high-quality lists of active Amazon UK sellers that my sales team can contact.

I am primarily interested in sellers operating within:
Beauty, Skincare, Cosmetics, Personal Care, Health, Household and similar consumer-product categories.

For each lead, I ideally need:

Amazon seller/store name
Amazon UK seller/store URL
Legal company name
Owner, director or purchasing decision-maker
Verified UK phone/mobile number (very important)
Verified business email
Website
LinkedIn profile
Companies House number where available

Important: I am NOT looking for generic ecommerce companies or businesses that might sell online. Every lead should have evidence that they are an active Amazon UK seller.

I'd like to begin with a paid test of 50 leads. We will verify the leads ourselves and contact them. If the data quality is strong, particularly the phone numbers, this can become ongoing work for hundreds or potentially thousands of leads.

When applying, please tell me:

How you identify Amazon UK sellers.
How you obtain and verify their phone numbers/emails.
Your price for a 50-lead test.
How many leads you could provide per week.
Please provide a small sample of your previous work if possible.

I'm looking for accuracy over quantity. Please only apply if you can specifically identify Amazon sellers rather than provide generic B2B lead lists.
