New Client...pleasure of billables

So I just landed a new client for a cataloging project. That they have a library of a few thousand volumes is great. That they have a cadre in that number that are quite special is great. That they want to consign some number to be sold is great as well. What I simply love, however, is their willingness…their expectation…to pay a billable rate for the cataloging/appraisal work. I know this should not please me as much as it does and I have certainly had a number of other projects that were billable and went very well. However, this is just something nice about a client who offers to pay for the time involved in coming to visit as scope the project as a whole. To be fair, he is a corp. atty and, thus, billable hours are like breathing. I like him anyway :-).
