Why only Adobe? Why not other editors that are equally as good?
I would also touch on some back-end stuff, PHP or whatever you use on the server as well as a bit of Database languages knowledge.
So to make it attractive, you would need to make it "Hours to suit" with a minimum expected work return per week.
You would be advised to have some form of contract of employment written up that also includes a couple of caveats where they are on a retainer until the client has accepted the goods as fully working and tested as you don't want someone to write code, get paid and bugger off and leave you holding a failed site. So you should be careful to ensure that the person you employ is going to commit to such an agreement when the time comes to resolve the errors / bugs in the code.
