Eu based professional Android developer, I have done similar app so many times, I can assure you professionalism and productivity.
The APP will be scale-able for your future needs, I can provide you with various option for recording to taking image and so on.
Please get in touch to discuss further, I am open to negotiate, we can set the Mile stone payment, the first payment when the project is 50 percent completed and on only 50 Euros and then full and final payment when full project is finished.
Thank you
Bari.
