For the time being, I would say magicaldice's campaign(they count nearly every post, at least they used to), bit-x campaign (due to unlimited posts) and if you are accepted, coinoindex campaign(which is AFAIK not available for new participants, so a bit low chance there).
Playtodos was too doing good until they closed.
Lastly having a look at your post quality, I don't think many signature campaign would deem you as a good poster, so Magicaldice:
https://bitcointalk.org/index.php?topic=1167837.0 is currently the best one for you.
As for campaign manager coming
to you until you either :
1) Are on default trust
2) Accept low rates
3) Make quality posts
4) Make many posts , not much quality but are reasonable according to the discussion
5) Are a popular person in bitcointalk
So very low chance of that happening.
