Finishing touches to our existing website

We have an online tutoring marketplace that links tutors worldwide with students worldwide. Our tutoring marketplace website is already live. I need some testing and addition changes. We need a full stack engineer (MEAN stack programmer ), well as someone familiar with Linode hosting.

If this work is done perfectly, on time and budget I will definitely have much more work.

The most difficult thing on this site is to find competent and honest freelancers. Your reviews and price will be very important.

I need:
1. "Insecure site" message to be removed when visitors try to open up the site See uploaded file).
2. Total testing for a new tutor account and a new student account to be done and systems fixed as necessary.

I would like:

For Tutors:
- A new account set up
- Lessons inserted
- A lesson taken

For Students:
- A new account set up
- A lesson chosen from the new tutor
- A lesson taken between the new tutor and new student.

I would like one video taken of each stage for tutors and a different one for students so that I can show it to new students and tutors.

I will provide all coding to successful candidate.

The price, time to deliver and reputation (from reviews) will all be extremely important in my decision.
