Before starting the development work of apps like Instagram or Facebook you should carry out the customer expectancy survey and match your offering against the expectancy which will give you an idea of the performance of your offerings.
If the survey results in a positive outcome then the next step should be to hire professional developers to develop an app like Instagram and then in co-ordination with them develop a plan and decide on the feature and technology for your app development.
