Server Help Needed

Ive had my minecraft server open for a month now and I never get any players and I am about to shut down my server. Donations are needed to run it and I even let players donate for staff! I coded the server (Professional coder did the work for me) and I get not alot of players. Can someone special with great ideas the help me make my server get more players?

Server IP: 64.237.54.203:25650
