Hi, i have gone through your project's description and requirements and its quite an easy task for me, so feel free to contact me so that i can start working on it.
I have worked on similar apps in which i had to show different routes to users depending on their Starting point and destination point, and have integrated Google Autocomplete in the apps as well. Feel free to checkout my profile and portfolio and let me know if you have any further questions. Hoping to hear from you soon.
Regards,
