OpenCart Modifications

We are currently building an OpenCart online shop. We are using a paid template but we need some little layout modifications. They are all related with CSS and HTML. Modifications are like changing category list style, adding images to dropdown menus. We also want to show brands related with product on product page. There maybe some paid addons for these modifications but we want to work with a developer. We may need to work in the future again. So we are looking for an experienced developer. Price is important and budget is limited. Thank you to all bidders.
