Few advices how to make your RP server work!

Something to add. make sure you go with a quality server host. while hosting your server yourself, or buying the cheapest company is cost effective, ultimatly it will be your downfall. Self hosting requires an active internet connection and PC 100% of the time. if your internet cant handle the people connecting, you will experience heavy lag on your end. Buying the cheapest host possible may seem like "What can be the bg difference" thinker, but there actually is. I personally recommend Crident networks, or GMC Hosting. both are inexpensive, cost effective, and give excellent servers for the price you pay. any company that charges by slots, is not one id personally recommend, but it's up to you.
