I would use MMS APIs to make this a convenient reality.
I think your app in its current form has the wrong form factor.

Regarding form factor our plan is a responsive site that down scales to touch devices. That will cover both desktop and mobile well.
Just tell the customers "Text us, email us, fax us.... etc..."
But by and large we would accept applications any way they would want to be send but I question the value of building MMS in the MVP. This would cater to the 'camera enabled non browser devices' and our research shows this is a tiny slice of our audience. However this is a quick thing to build so as we progress research on our target audience we may change our mind.
