Hi,
I developed an app ("Empire Steak"), which sounds similar to what you want.
Behind the counter, an iPad was used to track food orders, and a customer-facing iPad showed order progress.
In your case, you are using digital signage, rather than a second iOS device.
The big question is, how does iOS communicate with your signage - we would need to talk about that!
I develop apps for iPhone/iPad and Mac, using Xcode and Swift.
You can see some examples of my work, and client reviews of my completed projects, on my Freelancer profile page. Further information is available on my website, notyou.co.uk.
It looks like you may be new to Freelancer? Before starting the project, there should be a clear understanding of the details, the deadline, and the milestone payments.
If you'd like to reply to this message, we can discuss things further, before you make your decision on awarding the project.
Depending on the complexity of your design, and the details of your digital signage, we may need to adjust my bid amount, up or down.
Best Regards,
- Rob Dixon.
