I've been thinking awhile that i might make a similar post to this one at some stage. Not being a programmer and beginning a startup that requires programmers without one at hand already is quite difficult. That being said I personally would never do a pure software startup. However of late i've come up with plenty of good business models that have a software element but also requires skills that I have outside of what they try to teach in a commerce degree. With that situation it seems a more equal partnership and also allows a greater sharing of the main company functions, something that helps down the road. I would suggest you look at doing a startup where you can really contribute to the actual creation of the product/service.
The other thing about writing these pleas for help/founder is that you've got to show a little leg. "Software as a Service business" is hardly going to bring the hordes knocking down your doors. Even if you don't want to give your ideas away at least narrow down the areas of your interest because your much more likely to attract someone good if they already share that interest.
