This is a fairly trivial piece of software to have written for you, but I'm not aware of any off the shelf packages - which doesn't mean they don't exist. I'm guessing you probably don't want to hire a developer though, so here are a couple methods that might work for you:
1. Low-tech - setup your filesystem so that each model has a directory with his/her name. In that directory you could include a text file also carrying the model's name with the details - contact info, etc.
For example:
- C:\ Photos
- Jane Doe
- Jane Doe details.txt
- [Photo shoot 2007-08-01]
- [Photo shoot 2007-08-12]
- John Doe
- John Doe details.txt
- [Photo shoot 2007-05-01]
- [Photo shoot 2007-07-20]
2. Create an Excel spreadsheet and setup a hyperlink to the model folder. For example, let's say you have a column called Model Name and you want to click on that to open that person's photos.
- Type the name into the cell and hit Enter
- Right click on the cell
- Choose Hyperlink... from the menu
- Type the address of the photo directory in, for example C:\Photos\Jane Doe\
This of course assumes that you've actually got MS Office, but I imagine any version of Open Office or other spreadsheet software would have similar functionality.
