I will require more information for the poster, such as the planned size to print, information on the business to add to the poster, and a few products that could be listed, but i have a simple concept.
When listing the products on the poster, with a minimal design that will direct the attention to the product as well as make it desired.
Hopefully, you intend for the poster to be in english, as i noticed the work offer is in english, as i unfortunately don't know other languages spoken there. However, if the information and translated text is provided, i might be able to fit it into the poster as needed.
