Camera ready artwork

Hello, I am looking to have artwork converted for print (camera) ready files. The artwork files should be in JPEG and PDF format, and should be sized somewhere close to what I have in mind. I need my paintings converted for print quality Raster files. I don’t have time for to figure out software and such in order to have more time for creating. I will be slow to start but plan to increase the volume of work over time. I need somewhat quick turn around but mostly need reliability and integrity. And a little advice with my printing goals would be helpful. Also if you can give me idea on your fees. Thanks in advance for your help!
