Though it will be in January I’m a interested in preparing a visit of someone who might be my 1st customer.

After listening to his last CD (and having been asked to give my opinion) I told him about some of my ideas regarding arrangements and vocaltracks. Somehow he got interested as he was also looking for a studio and so we scheduled a meeting.
I was wandering how you deal with customers that not only want you to engineer their production but maybe also want you to take care of arrangements or maybe even deliver compositions. Coming originally from the composing-/musician side and not from the recording world I am not sure how to deal with a project where you would compose/arrange in a studio. Should I just be happy about a 1st customer wanting to use my studio and give him the time he needs in the studio or should I keep the recording and composing/arranging activities separated and ask him to send me some ideas that I can work on?
Thanks in advance for your thoughts and as always this newbee is happy with any suggestion.

k.regards,
pedwin
