I recommend [link] They are concise'd book and they are all great books (they come as audio book so you can listen to them when you are on the bus, in traffic, editing boring images. It is worth the money. I hope that helps.
I have used two printing services - one on photographic paper: Photoworks, and one that does high-quality Giclee printing on archival quality paper: IONA Print Studio, in Provincetown, MA (on Cape Cod). These are probably too far away for you to use effectively, however maybe some of your American followers might find them useful. Commercial services like Photoworks have issues, especially with non-standard cropping, so I usually send them uncropped photos and crop them manually my self.
For a while I used an on-line backup service, to store backups of my photographs, but they went out of business and shut down. Now I use an old computer at my office which has FreeNAS installed on it as an FTP server. I back up everything (work-related and personal) to that.
I also like this other brazilian photographer: [link]
And, probably someone had already pointed this site, but I peek it some time ago. Maybe help you in something... I hope
Really sorry for not being a better support. Y_Y
