In taking pictures for a photo business that I am starting, is it better to provide proofs or a disc or both?

Depends on what you have available to you.





A lot of photographers put small, low resolution pictures on a web site to speed the process along (plus reduce costs - no CD, no envelopes, no postage). Others will send a CD.





Paper proofs are the most expensive way to go. Depending on your client you may need to do that. Most people are familiar enough with the internet to work with digital proofs, but if you are taking photos of a 50th anniversary party - think real photos!





If you are using digital - whether web or CD - consider watermarking them.
