Greetings!
About your project:
Our specialty is UE4 games, we can definitely make the conversion both for Android and iOS (once you have an apple developer account). We have developed many mobile apps inside UE4 before so this would not be a problem. About the second project, we need to make some researches to check if it's possible to create a download system for that, we can answer you when you contact us for the first project.
About us:
We are a couple which consists of a programmer and a level designer. We got picked as preferred freelancers because of our UE4 and Unity reviews and we are sure that we can do a great job for you.
Final words:
Please take some time to look at our portfolio and profile page, we are sure that we can do the best job for you.
Thanks for your attention,
Rafael and Monique
