Portal Industrial Cartagena Colombia - Forum - Contacts

I have a farm and I have been dealing in the tomatoes stock lot export for a long time. I wanted to expand my business more in the country so I decided to get a website to make awareness among the tomatoes stock lot buyers from everywhere in the country. I need help in knowing the areas where there area more buyers. It will be a big help if someone can kindly let me know the area that I should start to do the marketing so that my business started to expand. I will be so thankful for the positive responses.
