I'd go with the Planar Binding route described above. Why? Strategy vs. Tactics.
As a Sorcerer, you are wonderfully flexible on the "tactical" scale. However, you are woefully rigid on the "strategic" scale. Planar Binding fixes this to a degree -- you can spend resources (comparable to what a Wizard would spend scribing, making wands, etc.) in advance, to prepare for anticipated scenarios.
With a Cleric backing you up -- or, heck, a staff of magic circle -- you can bring in whatever help you need.
