correcting fully responsiveness behavior of website

Hi Folks, I am looking for a Joomla expert to correct the responsive behavior of my website. Basically I had bought a Joomla template on 3.x version which was fully responsive & installed it using quickstart ( This installs the sample data as well & hence gave me an exact copy of their demo website ) We then customized this template. The main changes were: -increased the size of the 'top-bar' -changed the logo -changed the search bar size & text -removed the background image in 'header' position & few other unwanted items. -Introduced a Menu bar in the 'top' position using DJ -Mega Menu. After these minor changes were made, the responsive layout has been affected. See screenshots attached & this will give you a picture of what I am talking about. Now, I'm looking for an expert to correct this. I believe this should be rather quick piece of work, since the changes were minimal. The template on 3.x; the layout & the extensions used are fully responsive. P.S The project wouldn't suit someone who needs bit of a learning curve as I would need this work completed in 2 days time.. Past experience in building responsive website will be a huge plus here. I will be providing the website url, ftp details, demo site address & more information to the selected freelancer. Thanks.
