Question:How to make a Flyff v15 Pserver?

I want to make a v15 pserver but i have no knowledge about servers.
If anyone could make an easy guide for me that would be great.

Also please don't copy other people's guides.
I've tried them but i dun understand them
If you could grab a guide and put it to more simpler terms that also would be great.

I need to know the following
Setting up the server
Changing rates
Selling certain items at NPC(greens please)
how to start up the server
how to make an account

I don't need a guide for websites or putting it on hamachi
I'm planning to just use a v15 pserver connected by LAN to other users.

also looking. if you find a good and easy one please email me :D [Only registered and activated users can see links. Click Here To Register...] if u end up getting a server on ur own id like to join and be GM :DDD ty
