I agree with @safetyzone There are several online programmes or fitness experts I'd recommend:
MegSquats Stronger by the Day (a free week, then I think it's $USD90 per year - very good value. But no individual coaching. I use the programming when I'm away from home and my home gym personal trainer.
Rachel Henley HenleyFitness - a free programme, but also an online coaching programme. Have a look at her content on Instagram. A friend of mine uses her programming & loves it. Warning: she swears a lot & the innuendo is of f the charts, but her advice is absolutely sound. Her personal form as a weightlifter is v good.
I also love Shiv Wilson on Instagram "Wilsoncoaching" - excellent content, and she runs an online coaching programme.
The online coaching which includes individual check ins & form checks is probably more expensive than SBTD, but might help you start out.
OTOH, PureGym often does deals on PT sessions - could you get a series of sessions to establish & learn about a good training programme?
The main thing for any resistance training programme is progressive overload - you train your muscles by adding something - more weight, more reps, more time under tension, greater range of motion, and so on.
