Wordpress Plugin - Special Contact Form

I need a WordPress Plugin to create a Contact Form that send messages to e-mails that I will set on plugin configuration panel and write a post with the informations from form (this option will be set on plugin panel: only posts, only e-mails or boths) . The plugin have to create a contact form on a page, with 8-10 text fields. I need to specify the name and maximum number of characters of the field. The plugin will send e-mail message for e-mails that I will set on plugin panel. Each field will have a description set on panel. Post Category generated can be set on panel. Plugin need to have a widget where I can set a text and a link to the contact page.
