We have a ecommerce website, the site has been building in the half way, the freelancer was disappeared, the template has been installed, only need to complete the project, The ecommerce site is opencart. Please read carefully if you are interested in this project. Things needs to be done for the project : 1) To customize the template color, I will give you the sample ,so you only need to follow it. If you have any good idea on customization, we will listen. 2) To upload the product , it needs to upload manually, because we didn't do any product data by excel, so the product data can't import directly to website by excel , about 50 products need to be uploaded manually to the site, and other 10 products file above have been backed up by previous theme, so those 10 products you only upload it directly on the site. But need you to adjust the image size or re-do the product image. 3) To design banner, we hope to find a canditate who has experience for building ecommerce site ,patient and good at graphic design,especially design banners. a) the sites has 10 product categories, you need to design 3 slide banners for product categories , the slider is animation, it has devided 3 slide for one slide banner. b) you need to design 10 small banners , we don't know the size of banners, you must figure out yourself. c) you need to design 4 images for shop categories. 4) You need to design the logo . 5) install some extensions. p/s : We hope to find a serious and responsible freelancer, if the template is hard to customize or come out some conflicts, we hope you to be honest to us and let us know what happen for the site instead of escape or disappear.
