This is a welcome addition to the tech startup space. I have a different twist to the UI and functionality hiccups discussed by the thread. This will work in Nigeria if perhaps you can take into consideration the Nigerian factor to tech, startups and apps.
An average Nigerian will ask ‘what is in it for me?’. ‘Why should I use my money to support you?’. ‘Who are you to me that I should give you my money to start a business?’ Even when an idea is novel or socially-beneficial, Nigerians only support or get involved with people they know and can directly or indirectly benefit from. This might sound like an over-generalised stereotype, but it is sadly true.
My solution and recommendation is that there should be an option of a ‘reward system’ in place. So for people who wants to benefit something from their ‘hard-earned’ money, look into the option of actually working with startups to ‘crowd-raising’ equity from people who are interested.
I am open to more opinion on this. If you guys can look at this and other areas to tighten you business model, then you will succeed
