Snake Deity builder (beginning construction, 3.5)

[Darkaurora00]

I am in need of assistance in making a character that can start off as a lv. 2 character and be properly built deity as soon as possible. This isnt to become THE deity of awesomeness, just a roleplay idea i thought would be fun.

What exactly could i do to make a mortal turned deity without using punpun cheese? for appearance im hoping for it to end up like this.

What are peoples thoughts? any starting suggestions or advice?

Dragon Ascendant but that requires you to be a dragon and have a BAB of +30

Finding a way to polymorph any object into an abomination permanently

Convincing a deity to make you a proxy.
