Custom Contact Boxes in Joomla for existing site

Hi, I have an existing site that I need to have contact boxes for it. The site does not have backend. I need contact boxes on the site. 3 in total. One on the contact page and 2 long narrow ones on the site of the website. I think they will need to be in joomla to capture the info. I have attached an image of the way the site looks now and a very basic way I would like the site to look with the added box. I would hope the designer can make it look much nicer than the example
