I have a lady that has graciously offered to do the calligraphy on my invitations for free. She initially said that she'd do 100 for free, as a wedding present, but then changed it to up to 200. I'd really like to pay her for any over the initial 100, but she won't tell me what her rates are. We have inner and outer envelopes. What would that cost if I were paying someone to do it? I'd also like to get her a nice gift. Do you all have any suggestions?
