I need help with my 1000p army

Hello dear brothers and sisters. I am still quite new in to warhammer and I would like to get some help with the 1000p dark angels army that I want to build.

So far I got supreme grand master Azrael, thats 215p.

Right now Im thinking of getting "deathwing knights" 235p and a "primaris redemptor dreadnought" 200p, tell me if one of those two are a bad or good idea.

Outside of that I dont know what eles I should get to get to 1000p, maybe the combat patrol but I heard its not that great and I wonder if theres a better a alternative.

Thanks for all the answers and suggestions
