I have a website for listing and selling domain names. Buyers contact sellers directly so no auctions or fees.
I am looking to start selling domain names using my own domain management application, same as godaddy or 123-reg. I found a stable open source project, domainMod but I need to code everything myself using slim php and build every module on the top of my current website.
My question is how practical and easy to do this and is there a ready alternative, SASS or commercial or open source
