Negative! Unless this place gives you an ICC file to soft proof. You are going to tag/convert all your files to srgb.
Is your monitor calibrated? No...?? don't even worry about color management. If yes... here is a simple workflow
if your workspace is AdobeRGB, and your camera files are SRGB, the first thing PS will tell you is that it is mismatch. You'll have 3 options. In case of a file is already tagged sRGB, I will work under this space...make all edits and save
If you are workflowing from ProPhoto, I convert down to AdobeRGB. Make all adjustment and post-processing. once the final is ready Convert to sRGB, and save file, and send it to your printing place
If the file is already tagged AdobeRGB, it won't ask for anything. You should do everything you need (post-processing), and than CONVERT to sRGB.
If your printing house DOES have ICC profiles, than the workflow is different.
