Sustainable Selly

We want to develop a website which aims to influence consumer behaviour to become more sustainable. We need a website as well as a chrome extension. We want the website to introduce our idea/business as well as be able to input your location and it will give you sustainable shopping locations proximate to your location. We would also like the user to be able to log in and input their shopping preferences and then use that to promote similar but sustainable options. Alongside the website we would like to create a chrome extension which will track certain key words searched and pop up on the side with an advertisement for a more sustainable company with similar or the same products.
