This request isn't for me, but for someone the g/f knows. It concerns a poetry book, so I imagine there's less text (but more issues with spacing and indents).
I don't even have time to format my own work, let alone anyone else's. I like my own formatter very much, but he has orders backed up farther than the poet is willing to wait.
The poet is less patient than I am; but is willing to pay extra for a "rush".
If the formatter in question only does Amazon files, I guess that can be ok too as long as it's complete and fast. The poet might be willing to wait some extra time before appearing on non-Amazon online venues, if that involves getting their book online a little faster.
As far as I know, there are a lot of competent formatters out there --- but there are also a lot of self-pubbers keeping them very busy. I would think that competent formatters without a backlog would be awfully rare right now, but if any are out there, I guess Kindleboards is the place to find one!
