Hello sir
Hope are you well there
I am 5 years of experience in android application development and i have seen your project requirement and I am interested on this.
I have developed taxi, e-commerce , social, and other application and all is live on Google play store.
I will do your application changes with minimum cost and less time and you only create and release payment when you satisfied with my work.
Also check my portfolio to see my work.
So send me message for more discussion on the project.
Thanks
