You have just completed a proposal for a new potential client. Does it present the quality of your work well? Would you like someone else to look it over to make sure it is presentable? That’s what I do, to make you look as good as you possibly can. Concerned about confidentiality? I respect your need for privacy, and I won’t share anything.
Putting together a new marketing campaign or website? Send the text to me before presenting it to your designer; this will save you money by having the cleanest text possible before the designer makes it look just right. (No costly reworking or reprints.)
