Electrician Booking App Development

I'm looking for a skilled app developer to create a platform similar to Urban Company, specifically for booking electricians. The app will connect users with our in-house electricians who will visit their homes to resolve issues.

Key features needed:
- Appointment booking
- Issue description form
- User authentication with social media login

The app should be available on both iOS and Android platforms.

Ideal skills and experience:
- Proficiency in mobile app development for both iOS and Android
- Experience in creating user authentication systems, especially with social media integration
- Familiarity with appointment booking and issue description functionalities

Please provide examples of similar work done and estimated timelines.
