Change theme and banners of an existing Joomla Template

Hi, We have purchased a Joomla template for which we need to change color of the theme and we need to create some new images for home page banner. We will provide a sample PSD and we need same color theme in existing template with some other changes. To be very precise - 1) Change theme color of existing Joomla template (this is a Joomla 3 responsive template, hence new changes should not impact existing layout). 2) Create 4-5 banners related to Yoga / Meditation and spirituality 3) Change 4 icons as per requirements 4) All changes must be reflected in Home page and inner pages. See attached doc file for more clarifications. Freelancer must be having experience in Joomla. This is a small task and should be completed in 2 days and we have very limited budget for this task.
