Well first off, the 4 haemonculi on jetbikes probably aren't going to work. Even with the high toughness they are probably going to be taken down in very easilly in HTH. Haemonculi on jetbikes work best when you give them destructors, so they can fly around burninating the enemy.
You also have only one WWP = very, very bad. A smart player will wipe that warrior squad out very quickly, denying you the chance to open it. Of course, in a 1000 point army you don't normally have enough space to throw in two, so the next best alternative is to give it to a WELL PROTECTED (read: shadow field) haemonculus or Lord.
I really prefer to use WWPs in games larger than 1000pts, but if you're intent on trying it out, I'll see what I can do;
My suggestions are that you should take out:
2 of the haemonculi
The reaver jetbike on one of the remaining haemonculi
The Wyches on foot
The Ravager
The WWP and sybarite on your warrior squad
...giving you about 450 (?) points to play with.
You should then add...
A destructor for your Reaver jetbike haemonculus
A WWP, Shadowfield and destructor for your Haemonculus on foot
2 Blasters for your warrior squad
A succubus w. Trophy racks and an agoniser for your wych squad
10x Warriors with 2 Dark lances
...leaving you with about 200 (?) points.
From there, you could do a couple of things with the points, but I would personally take a 10 man raider squad with a splinter cannon, blaster, sybarite w. Agoniser, and a horrorfex (about 185 points), and them pour the rest of the points into filling out your 2 warrior squads on foot.
The list you should have after that could probably do with a bit more tweaking (IMO, I wouldn't take the wyches at all in 1000 points, but I suspect a few other guys would disagree with me on that), but it's a very good start.
BTW I'm not absolutely positive, but I think your wych squads may be less points than you've put there. I suggest you double check those points values, as well as the points values for your other units (like those jetbikes).
