Crear una plantilla de Wordpress

The idea is to create a template on Wordpress that will work as a comparison engine. The idea is to offer several engine comparison templates for several kind of products. The templates will be used by individuals that would like to open a page where to have a comparison engine. These individuals will be responsible to update the companies/products links that have to be compared, and maintain them. The data of all comparison engine sites will be sorted centrally, and we will also track the links and the activity in those pages. We would like to get a budget for developping a comparison engine like this one: Un ejemplo de uno de los modulos es: [login to view URL] In this case the data from the companies compared is sorted and filtered according to several criteria and inputs. In addition, the template is customizable (layout shape, colors, logos, etc), and you can compare two or three objects one-to-one, and click a link that would conduce to the product to buy it. It needs to be compatible to a broad range of devices and browsers. The design needs to be neat, simple, fresh, modern and fast to use. It has to be modular and it should enable to add new functionalities in the future, such as registration of users, etc. Looking forward a budget for this specific template sent, please also send me an example of comparison engines or websides you have designed in the past so that I get an idea about who is your work. Thanks and regards
