Same to you bro...I been playing different minecraft servers for years and decided to make may own servers and work well..until i decided to add some Co-Owner to help me improve the server but instead of helping me, i got banned and kick from my own server...I trusted him so much that didn't see his true intentions to hack my server...well as you say, your looking for a co-owner to help maintain the server with.
Thats fine but just be careful of scammers and get a good Developer instead of having co-owner.
