New site coming soon?

We're currently building an email list of web agencies for one of clients, using as our starting point and building information around core details by using Google, Facebook and other online directories.

What we find surprising is the large number of agencies listed who:

a) don't have a web link from (OK, so Yell is not everyone's favourite online directory but surely if your business is web sites, you'd have a link to your own site?)

b) have a web link that doesn't work or go anywhere?

c) have a holding page claiming that there is a 'New site coming soon'?

Is it enough for these that fall into the latter category to claim that they have been so busy building sites for other companies that they just haven't had time to create their own?  

Or does it just mean that they are not very organised?
