Build me a special needs recycle fun run web

This is a virtual fun run web app like [login to view URL] that comes with free download of app that can detect the exerciser's running details and send SOS that they fall down to their emergency contact number with the apk file provided by me. I need a person builds the web for me that launch free virtual fun run app monthly with different theme to promote runners exercise indoor and outdoor. The rewards of the achieved goal of 150km and above will be rewarded with clean recycled clothes for the special needs including learning disabled children and adults. This web must allow me to become web administrator to add new themes of each month's running events
