I been looking at opencart multi-vendor but it is serioulsy buggy and i doubt it was tested before release. The top quality shops I found have extensions that are expensive. It looks like multi-vendor is a serious task from those prices. I was told developing an extension for one say presta is a cheaper option? Since my hands are tight financially, I can't afford to spend a lot. What do I do to just have a running app to show to a possible investor who showed high interest?
Perhaps you can do a graphic mockup of different screens to show how the marketplace will look and function. There are several products that allow you to do this for free or inexpensively.
Yes, actually I do. I did create a functional sample with woocommerce and paid for an awesome theme personally. But the investor's close advisor, who I didn't meet, advised wordpress is not the ideal way to build an ecommerce application. I did a research on that and couldn't back his claim frankly.
Agree with Elizabeth Mannette. Part of the question is where you are in terms of the business. For instance, do you already have potential investors? It may make more sense to frame out the proposed app rather than spend more money on creating the app.
