My recommendation is for Blackthorne Pro, based on extensive personal experience that I've yakked about in numerous other threads.
In this case, I'm thinking the ability to use templates, automated image handling, sales tracking, and email features are going to be the most useful. The ability to update all listings, running as well as scheduled, will also come in handy. And the flat fee, regardless of extent of use.
For a designer template, fully Blackthorne integrated, talk to Sally, who also posts here from time to time. Graphic design and web design in a single package -- can't beat that!
Point is, you want to use a tool that's going to automate the parts of your business that are causing the most problems today. Things like terms, updates, embedded images -- these are all things Blackthorne does well. Get those worked out and you can start concentrating on growing the volume, rather than spending time working on problems more easily solved via automation. Computers don't get bored -- they can do the same dull things over and over and over and over....
Good Luck!
