I will create a PHP contact form for your website which will send an email with all the data from the form to your email when someone submits it. There is simple but very effective anti-spam checking integrated but I can also add Google reCAPTCHA if needed. The form has JavaScript input validation. Also, the form is AJAX which means a visitor will be shown a message that his submission was either successful or fail. I can add redirecting to other page if needed.
For 5$ you will get
1. Responsive PHP+AJAX contact form with JavaScript validation. The form will contain few fields(for example, name-e-mail-message)
2. I will install the form for you.
