Advise seeking.

Hello. Im thinking of app idea (similar to freelancers platforms but trailered to custome needs) but dont have a background in such matter. Not from ghana and the idea is also not for ghana. Trying to see how attainable it would be to 3rd party with unbiased opinion and good technical experience. And want to know basics needed to be on top of things in case decided to go through with it. Id like to have some questions to know to ask even if this one does not work or chase new ideas) Ex: costs, support, licensing, backup, NDA,... Etc?
