Hello Greg
We are a team of designers and developers with expertise and experience in Photoshop, HTML, CSS, PHP, AJAX, JQuery, Angular JS, XML, Wordpress, Joomla, Shopify, Bootstrap, CodeIgniter, Laravel, Google Map API and MySql.
We have delivered many Wordpress sites and all of them are responsive (multi-device compatible). I will share urls once I hear back from you.
I have studied your site and am confident of delivering a responsive Wordpress site that looks exactly as existing site and has same contents. If you want anything different by way of layout, contents etc. please share details.
I ensure a very thorough job and also support if you need changes / enhancements in future. I look forward to hearing from you and working on the project.
