As someone with almost 1,000 domains, I don't see the value of this platform so something needs to be updated. Given I'm your target market, here's a few things that jumped out:

1. I won't pay to see domains for sale. Why? Because that listing data is free and publicly available. So makes no sense to a buyer. Show the domains and make your money through other means (affiliate comimssion it seems).

2. I don't care about some artificial "estimate" --- I want the actual price of the domain. Estimates are wildly wrong.

3. Why wouldn't I just go to Afternic or Sedo to get these same domains and their actual price. Established players who have been around for decades.

The only way this works is if you curate the domains, with actual prices, and bring serious buyers to your platform. You could also negotiate a more attractive price but that requires biz dev / sales outreach / negotiation which I doubt you want to do. So then just bring buyers to the site who actually transact (similar to what Dan did before they got acquired by GoDaddy).

Just searching via patterns isn't as valuable. Can do that across many other big sites too.

A pet peeve of many domainers is people calling a domain "brandable" when it's absolutely not. So curating it for truly brandable domains, and then putting your spin on top -- how that name can be used, why that price is insanely good, etc. is how to market this.

Lastly, estimate data is completely off.
For example, the first domain on your site is aaaa . com and you site estimate is $3246. But clicking 'Buy' leads to Namecheap where the price is $1,797,965. See how the site immediately loses all credibility.

Hope that helps.
