Well it just depends on your retail niche and where you would like to set up shop (what city in JA)? Who would you like to target? The needs vary based upon many factors! I would never recommend starting any business without a plan, even if its just basic to begin with - it will help sort out the details for you.
I am a business consultant focused on Internet Marketing: blogging and training. I have an MBA in Finance and a BA in Business Management and Operations from universities in the US and after 13 years in corporate America, retired, now running my own online business. I absolutely love entrepreneurship and helping others find their way.
My opinion is that our new economy requires us to leverage technology to the fullest. Working online provides freedom and a global market...it's awesome and anyone can do it! Feel free to email me for more information: vanessa(at)entrepredivas(dot)com
One Love! Vanessa
