Contact Form with weekly limit

[mtb]

Hi,

I wanted to know if it is possible to have multiple contact forms on my blog that basically send questions to different email accounts, but also have a limit of say 5 emails per week to each account.
After the limit of 5 has been sent for that week I can display a message stating the weekly limit has been reached.
I need to this as I am trying to an experts Q&A section but the experts only agree to 5 emails every week and don't want any more emails than that.
I was thinking about using the Contact Form 7 plugin for Wordpress for the multiple email accounts bit but don't really know how to do the weekly limit.

Any help with how to do so would be much appreciated.

Thanks

basiclly:

store the count of emails sent somewhere (probably a db),add one to it every time an email is sent also check if the week is up if so reset it.

check the count value to decide if you want to display the limit message.
