Hello BHW! I am Ruslan

Hello, guys, my name Ruslan.
I'm backend developer from Russia. Also i'm interested in SEO. Had long time experience with searching drop domains.
Now working on my project(bestdrop.io) to find drop domains with backlinks from trusted websites like Wikipedia.
Some days ago made MVP available for public.

But I have problem and some questions.
I already parsed more than 1400 drop domains from en and ru wikipedia. But if I'm going to sell it to people i can't show domain names before they pay me
So I need to provide some metrics about domain before. Metrics like ahrefs dr, referring domains, baclikcks, or majestic tf, cf and etc.
But to get all this metrics it is expensive. The cheapest service as I understood majestic account for 50 Euro but it only tf, cf, website topic, backlinks.
Now I found some websites where you can get metrcs for free but only few metrics and limited amount of websites.

Maybe you can recommend me some services? Or I really need to buy Majestic?
Also open for feedback about my service.
