I recommend you to try Cheap SSL Shop Reseller Program https://www.cheapsslshop.com/partner-program. They are offering huge benefits to their reseller partner, and also you can buy SSL Certificate for your website at the lowest price.

Sorry, reselling? How does this work, exactly? Would you find an upstream CA that is trusted, implement automation around their API, and sell certs?

Why would I pay you instead of just using the upstream vendor?

Why would I go to the trouble of dealing with you instead of a conventional provider like GoDaddy or Verisign?

What about Let's Encrypt?

Ditto for @jackfraser's comment.

In the Let’s Encrypt era who is going to spend money on a certificate?

Many businesses can't use Let's Encrypt for various reasons. I am not talking about certs just for someone's personal blog. I don't think Let's Encrypt can provide equivalent functionality to an EV SSL cert, for example.

find vendor, sign up for reseller account, grab api keys, churn our ssl certs using favorite language, create front end to site, and sell. Maybe you'll get bought by Symantec, who knows -that's the sad and typical end for that dream

Would not make me sad to get bought up (lol). My goal is to make money not sell certificates as a hobby. Do you have experience in this area? Care to share? I am just interested if reselling is economically viable at this time. There seems to be a glut of resellers on the Internet. I am interested in first hand experiences to better understand the market place before investing time in creating my own site.
