I can make you a relatively simple one for just $5.
The Google play store is supported by thousands of android devices so by expanding yourself onto this market, you should easily be able to up-scale your business.
Hiring a programmer somewhere else would easily cost you ten times what I charge.
It's not too hard for me so I can usually get back to you in 24 hours.
Upon creation I will send you the QR code and APK file.
