change/add fields

Hello,

I am trying to add new fields to the product where the price is.

I need to put a text in front of the regular price, such as "Price w/o bp"
Also add another price after that which would say "Price w/bp"
And either before that or after, a new field that contains a date and is labeled "Sale Date"


Can someone please help me do that?
