The application submission (and payment) is the first step, which is what he must do before or by the expiry date of his current leave. Once he completes this, UKVI will give him several weeks to book and attend a biometrics appointment. During that time he can continue working and doing his normal activities in the UK.
Booking an appointment can be tricky, in some places it is difficult to find a free spot easily. UKVCAS are releasing free and paid appointments every day. For example, at the moment free appointments are released in the morning at about 9 am. They provide more guidance on the application homepage.
It is possible to find appointments in a few days after application. I would say he needs to be flexible in terms of choosing an application centre, some have more availability than others.
