First 40k tournament comming up.

I might be going to my first 2000p tournament in a few months, and I'm not quite sure what to run. I'm not quite at 2000points yet and are looking to complement my forced by then.

What I'm currently sitting on is.

An imperial knight, with everything except preceptor option. 2 Armiger warglaives Crawl Dominus 4 kastelan robots 5 skitarii rangers 15 skitarii vanguard One Dunecrawler

How would you guys go about turning this into a list with a chance at winning matches? Not looking for too level meta cheese, I just don't wanna be totally stomped.
