How to find full time cs-cart developers


Does anyone have experience in hiring a full time cs-cart developer?

(Note this is not an invitation for cs-cart developer houses to message)

Im trying to get a full time in house developer who can provide domain knowledge and add value from the beginning

The issue I have is php developers seemingly take a long time to get used to cs-cart (time I dont have) or they do not want to work using cs-cart due to outdated tech stack

Any guidance on this would be extremely appreciated
