So, since launching my facebook page (I sound so corny

), I've gotten a couple photo session inquiries, not many, but enough for this
really inexperienced picture taker. A few have been scheduled, but haven't taken place yet. I'm nervous about them, but I do look forward to them, since they're kiddie shoots (I feel comfortable with kids so far).
But just yesterday I got an email from one girl who would like some beauty/head shots. She's a make up artist and wants pics for her business. Wait, then she said her boyfriend is a DJ, and would like a photo shoot. Then she asks for my prices
Just reading the email makes me nervous. I don't feel ready to take beauty pictures of anyone, and lest am I prepared for a DJ's photo session (as in I don't have any equipment, studio access, nor experience with studio work). I plan to tell her no to the DJ shoot, and refer him to this fashion photographer I happen to know, but I'm not sure what I should do about her. Should I go for it? I'll tell her about my very, very novice work to prepare her, but then again, I think it's unfair for her to think I'll get her good pictures. I don't even know how to work with photoshop well

Uggh. I don't know. This is a really good opportunity, but the last couple of days I've been struggling with the fact that my pictures don't always look great, that I suck at PPing, and that I'm so shy for such an extroverted genre. This confusion is normal, right?
