I want to strech my ears?

So I decided I'm goin to stretch my ears to at least 00, and went and got my right ear pierced, but didn't know I wasn't supposed to get it done with a gun. So I wanna know if I should just start stretching now, or go get them repierced with needles? If I do get them repierced, I'm thinking 8g? Which would technically skip a few steps in the stretching process. What I'm wondering is what would be the better choice? And also how painful getting them needle pierced that size?
