Google Scott Christensen "Paint The Ocean". He specialises in seascapes & is exceptional, I have a print.
He has a online course, which I did sign up for, & he breaks things down quite well. Is probably structured more for established artists, but does give a good insight into the process.
The course can be pricey, but he does from time to time run discounted promotions. From memory usually around special holidays, eg; mothers day, father day & Xmas.
I went through the course, found it informative, but alas work got in the way of my artistic endeavours, but in saying that, it is a lifetime subscription, so once you sign up you get full support(so to speak).
He steps out the process that he goes through for each painting, which is quite simplistic & that's coming from someone who also failed stick figures 101.
