I am working on implementing GTD but one type of inbox item keeps holding me up.

I am a photographer so a regulary (i.e.) daily inbox item I receive are inquiries. Either by phone or most often by email. Calling these inquiries (prospects) typically takes more than just 2 min so then it becomes an action. The problem is how to do that.

I could put

Call john smith

However, since I don't actually know this person I have to go through all my inquiries (I get several a day) and find this person.

I've tried

"call inquiries'

but that really is more than one action

Here is what a typical inquiry looks like that is sent to me when someone requests information from my website.

Full Name: Munirah Abdullabhoy
Phone Number: 908-517-9143
Email Address: munirah_na@hotmail.com
Service: Wedding
Additional Info: June 3rd 2007 in Eagle, ID

Often the person inquiring won't actually give me the additional info

Any ideas?
