Quitting my job for full time courier?

I’m looking at quitting my job. Been in the logistics industry for nearly 10 years. Never been a courier.

Start Evri full time in my car 6 days a week then buy a van and expand business etc, I know it can be done.

I’m wanting to hear from full time couriers is it achievable to earn £100 a day? £600 a week minimum? I am willing to graft for it. What is the current state of play in Evri? I know in feb they do there yearly rate cuts. (I used to be a field manager for Evri)

Just concerned I won’t make as much money but if I don’t take the risk I will never find out.
