Get CS-Cart Multivendor site ready for go live

Hi, I am starting a business using CS-Cart Multivendor. It has a the Playground theme installed. ([login to view URL]) I need help to bring the website to the point that we can go live. This is mostly about the 'look and feel' of the website - configuration of the theme and making it look nice and professional and getting all the colors and banners right (I will provide photos for banners and wireframe of what homepage should look like). There would also be some minor look and feel changes so will need some advise to make it look professional and appealing. Although the 'Playground' theme is responsive, the menu on mobile does not look right so need to be fixed. Menu on normal PC also does not look right and needs to be adjusted. This is a simple initial job, but I would like to build a longer term relationship with the right person that can help me with changes and fixes on the site going forward. I look forward to hearing from you! I am based in Cape Town, South Africa. If you are interested, I will provide the domain so you can have a look at what needs to be done so you can provide input and a time estimate.
