Welcome to SA:MP.
If you want to get started with a GameMode, you can just get a ready one from here:
http://forum.sa-mp.com/forumdisplay.php?f=71
Then there are a couple of other links you may like to visit. Starting from the FilterScripts, which will allow you to make different functions and add them on your server. Here we go:
http://forum.sa-mp.com/forumdisplay.php?f=17
But I highly recommend you to visit this link for FilterScripts, as there are better explained, with owner, and, there are only the most important:

Those are the plugins you're looking for, or, from what I saw on the topic title, you need them:

If you're an scripter newbie, you'd better visit this link below:
http://forum.sa-mp.com/forumdisplay.php?f=12
There you'll be able to ask for whatever you're like
or don't know how to do, and general SA:MP scripters will help you.
For second time, welcome to SA:MP, and I hope to pass a good time with us. If you need any help in advance PM me or just post below.
