Wordpress contact form/database options


I’m coding a wordpress site that has one primary quote form and submissions need to be printed to database which can then be exported each day (based on a date range selected). One other little feature is that users are cookied with a number based on how they get to the site. This data would have to be included with the submission.

Can anyone recommend a good plugin/option/set of codes which would accomplish this? I’ve looked at contact form 7 but with it’s database add-on you can’t select a date and since the site will get 100+ submissions a day there has to be a date selection option.

Gravity forms seems like the best bet right now. It doesn’t support getting data from a cookie but it should be able to be modified to do so.

Any ideas?
