Hello, before you hire someone else i would like to tell you that we worked on one solid website from scratch. this website is working as per your requirement (things are different but the logic are same).
In this webstite we have created 2 sepeerate user type. one is provider and second is shopper. shopper will post his/her requirement to buy handyman services , cleaning services, auto repair services , etc..
and the we will send this request to our provider , now they will refer requirement and then then will post his/her quote on the same. then shopper can see quotes / bid . so shopper can decide which service provider is fit in his/her budget. also we are able to show provider ratings , reviews. so shopper can easily decide it.
This website build in YII framework, mysql, android,ios.
I would suggest start will web application. once it will be done than we are able to make it on android and ios quickly.
I really would like to talk with you first. we have an experience with same functionality. I am totally ready to show you what we have done. Please let me know if you need any more details on the same.
One more thing i forgot to tell you we are able to give a dashboard to both users and messaging system for easy communication on our website. Admin will have reports too. we are in master with stripe,paypal integration.
