Hi

I just started to write a fantasy novel, i have about 57000 words so far and feel i am doing ok. my plot needs some help and my dialog is not on par with what i feel a published book should be.

does anyone have a good agent or editor they would recommend?
and would anyone recommend self publishing?

not to mention Book presentation such as synopsis, query letter and so on.
So if anyone has good tips on how to make a good Book proposal plz share
thx again...
