Please check my #42, #43 logo proposals with the olive branch concept. I thought that olive is a great Greek symbol not only because it's connected with its history but also because olive oil is one of its main export products.
Although the olive idea might be good, it is also restricting for two reasons 1. I am mainly a food exporter but i will deal with lots of different kinds of food 2. The company is a general trading company and i want to have to design a different logo later on when i deal with other products
