Modify website form. Max budget 15

i have this when you scroll down you will see a top bar, click on ask for a quote button, now you will see a form, i need the button of that form sends me an email with smtp method... its really simple.. with javascript and that in that same form shows a message of "message sent". In that form you can see also a field that says project deadline, i need that when you clic on that a calendar opens so the user can click on the date.
