Summoner Prc (Arcane) & Feats?

[Tirlanolir]

I'm playing a 2d Wizard with Augment Summoning and Spell Focus (Conjuration), who will eventually go the Alienist route. I am looking for a build and PrC that compliments the summoning aspect of this character. Does anyone have any suggestions or "house rule" builds or PrCs that I can run by my DM?

Your comments and assistance will be appreciated!
