Marketing of my App

Job ID: 32519166

Budget: £250 – £750 GBP

I had an App "The Pyramid Puzzle" developed for IOS in 2013/14. This was perhaps one of the most interesting and challenging App The App had reasonable success but due to the change in the version of IOS it now needs to be upgraded.
Ideally I would like to have it developed for both the IOS and Android and perhaps even Windows platform. But before investing in its upgrade I would like to be able to asses its full potential with a marketing/promotional company.
My objective is to make this App with an incentive of a prize where the winner of the correct solution would be put in draw for a large prize.
I am looking for interaction with a marketing company to discuss further.
