We are 2 freelance developers from Spain. Our expertise is developing Android and IOS apps. We also have done some migration over both sides, so we plan to have it ready in a week time, once you gives us the access to the web services.
It will be great to have all images and text needed also.
We usually do spanish apps, so you can look for taxiamano or chad2win to see examples of what we have done before.
Thanks
