Congratulations on your much deserved win @Startup weekend Lagos. While you bask in the glow of your win, let me hit you with some questions before you get a tan.
1. Data: your app is basically useless without the data of artisans. So how do you intend getting the data of artisans seeded into your app? And please don’t tell me artisans would do the profile creation themselves (I can see you have a form for that) you know why? Most of the artisans who are your target demographic are either illiterate and/or wont be interested in creating a profile on your app without them really seeing what value that adds to them i.e. monetary. And if you want normal users to create and rate profiles of artisans they have used, what would motivate them to do so? Whats in it for them to go through the whole process?
2. Business Model: Although your app is quite innovative at least in our local web space, but I cant for the life of me deduce how you intend making money from this app unless you want to go down the very well beaten path of Google adsense?  Provided you can generate enough traffic to cover hosting cost and other sundry costs with that, then I wish you guys luck.
P.S: I would be monitoring your progress over time. Congrats again sir.
 A very thought-provoking tweebate was the cause of this blog post and the major thing that was debated was how artisans details would be created on findjimoh.com and who would do the creation. Leaving that power to either the artisans or people who use the artisans would be a major fail, because you would be giving them the power to determine how fast your app would grow and how useful it would be to other users. At least in the beginning, do the seeding yourselves.
 Regarding your business model, a little bird just whispered into my ear that you intend making money whenever any artisan is recommended. I really don’t know how that would work. But a simple way I feel you can make money is by having a short code that anyone could text a requirement and have the top ranking artisan that matches that query sent back in response.
