'94 Accord rust spot

[Lobo]

Alright,
so I know that a big problem with the 94 accords (which I am the proud owner of one) is that they tend to get the same rust spot in the side of the trunk. Now, my question is what is a decent price to have someone fix it, and fix it well? (This would include bondo-ing and painting so it looks all shiny and new again...) Has anyone had this done to theirs before? I'm thinking it might be better just to fix it myself with the estimates I've been getting...
