Printing questions

I am so in love with the quality of the printed materials from SCS (especially the paper thickness!). I use them and refer to them often, much more than if i had to print them off myself. I would love to offer something like that to my own clients–a tangible workbook instead of just PDFs.

Could you tell me what company you went through for printing and binding? And did you create the worksheets yourself or outsource that? thank you!
