custom templates needed....

I create wedding websites for clients but am looking for a way to make it more automatic and less work for myself. I have set templates that clients are able to choose from. I would like clients to be able to change/add/remove content themselves. I will supply all templates, I need a script that allows them to edit different sections themselves. They should not be able to change the design, only text that shows up on each page. **I DO NOT PAY UPFRONT. I HAVE HAD A FEW BAD EXPERIENCES ON HERE ALREADY, SO PAYMENT WILL BE MADE WHEN PROJECT IS COMPLETED** If you cannot do the job, please do not bid!
