Clean up my server codes

I have a RSPS (Runescape Private Server) and those are written in java, so this goes to anyone familiar with those and/or who is good with java. My current rsps could be cleaned up alot more (codes are messy etc) and i could use someone who can make it much more stable (create a longer uptime) and can fix some errors. If you can do ANY of those contact me, it will all be done over teamviewer since i do not send my files unless i hire you if you are good. Thanks.
