I’m assuming you wanted some feedback to your idea so I will post my opinion. If not, then my apologies in advance for my opinion. The only thing that is personal is learn how to type, spell and format. In any business, professionalism is paramount, even if you are only submitting an idea to get started. Write a Business Plan and stick to it.
I know, I know you were in a hurry and it’s the internet, and who cares, ….but it does show a lot if you seek to draw people in. Reading that was painful, at least to me.
From a business perspective I’m sure it’s been done and being done now. The key I think is finding those niche items that no one else has, that everyone is looking for. I think you can find a lot of those items simply by searching through the classifieds.
I would not give up your day job unless your wife can support you 100% and won’t divorce you, if you totally fail. If she can and will support you, do it!
Nice car by the way!
