List Help Needed

So, my local game store owner asked me to join their 40k tournament at the end of October. I have never played 40k, but I have enough daemons from AoS I can build a list with them. The limit is 1000pts. I have the following painted and then I have a couple unpainted things I could paint up in the mean time. I plan to go in and meet up with some people to learn and practice over the next month. Any help is greatly appreciated!
