Greetings,
I have read the info regarding this project, and am in a position to get the job done.
Your project needs a USSD app, a mobile app and a backend to serve the apps.
You will also need an admin panel, for monitoring and control purposes
Optionally, you add a website too to the apps.
I have experience with android apps,USSD apps and systems control panels. I could also consider adding a website so your customers can access your services from browsers(we might need to extend the time though),so you have a complete package.
You have not mentioned payment integration (how the customers will pay to your escrow service),but we can discuss that later if you let us work on this project together. I have done projects that accepts payments in Kenya, so this is something I have experience on.
Kindly Reply so we talk and hopefully get started on this project. Looking forward to your response.
