Website Fix and Optimization

My website has several issues that need immediate attention and repair.

- Video Loading and Resolution: The most pressing issue. Videos are slow to load and need to be optimized for varying network conditions. They should load from low resolution and improve as network quality allows. Additionally, I want to use thumbnails from the first second of each video.

- Payment Integration: There's a bug causing 13% of payments intended for the admin account to not go through. Ticket transfers are also failing.

- Email Verification: The systems for email verification and handling forgotten emails are not functioning.

- Sold Out Option: This feature is currently broken. Once tickets are sold out, users should not be able to purchase more.

- Deployment: After repairs, I need the site deployed.

Skills and experience needed:
- Website optimization
- Payment system debugging
- Email system troubleshooting
- E-commerce platform experience
- Video player functionality enhancement
- Deployment expertise

Please address these issues promptly as they are affecting user experience and sales.
