Forget about whether your idea, which you haven't told us anything about except that it is e-commerce, should be labeled startup. What matters is the quality of your insight and the other person. If your thing is as lucrative as you say, break everything down and identify the parts that you will be responsible for so the other person will need you. Your idea is amazing if you can prove to a serious developer that your plan will quickly make both of you rich. Build a minimum viable product then iterate. These things often take longer than we think they will, which is why a technical co-founder in it for the long haul beats a freelancer incentivized only to complete the requirements you thought to list, all other factors being equal.
