B2B Lead generation in the "family e-commerce" niche

We are an online marketing agency from Germany and help companies in the family niche to grow through paid advertising.
This niche is quite small, which is why we are now looking for an expert who can research new leads for us in this niche.
We have the following criteria for qualified leads:
- a company from the family niche, which means products such as children’s clothing, toys, prams, but also products for family planning, products for parents, etc.
- from Germany, Austria or Switzerland
- have an online shop
- have a B2C area (not just B2B)
- preferably have an annual turnover of more than 600,000 dollars/euros
- they must *not* be retailers, but the brands themselves
We need:
- Name of the company
- telephone number
- E-mail address(es)
- Link to the website
Optional:
- Link to Instagram account
- LinkedIn company page (if available)
We have about 400 leads in our list so far. We can make these available for matching to avoid duplicates.
The quality of the leads is important to us. So we don’t need leads like H&M, TheNorthFace, or other companies that offer clothing for children as a subcategory.

We are looking for 50 Leads to begin with. If the quality of the leads is suitable, we are happy to talk about an open and individual payment.
We look forward to your enquiry!

Here is a list as an example of the brands we are looking for: https://docs.google.com/spreadsheets/d/1fCmd1IXRSEt0-n5dElOYn7HxAROppkD6sBU60qa0dfY/edit?usp=sharing
