Anyone know of a wordpress plugin for submitting order requests?

Hey there.

I'm designing a website offering my website design services. I have a decent amount of experience with Wordpress but it's always been fixing other people's websites, so this is the first Wordpress site that I'm making for myself.

I have a page for visitors to submit orders to me and have been messing with Contact Form 7, and while it can do the job this plugin is obviously not meant for what I'm looking to do.

In short, I'm looking for a form plugin that changes based on the customer's selections. For example, if they select the option that they want 5 pages the form will change to ask what they want on page 1,2,3,4,5 but for example if they select 3 pages then it only gives them text boxes to write details for page 1,2,3. Or, like if there was a Yes/No question and they answer No then they move on to the next question, but if they select Yes then another question appears related to the original question.
Also, if it can save the form submissions to the database instead of just emailing them would be a very nice feature.

This all seems like basic stuff but what I'm using currently just isn't built for it, so before I go messing around trying to find a good plugin that can do this I just wanted to see what you all recommend. Thanks!
