Just now your tasks are largely manual. While I don't suggest automated content creation, you can work smart. Automated content delivery is a different matter. It doesn't mean that all your posting duties disappear, but you can make a significant improvement.
Add to that, the first time through is a lot more time consuming. Not only are you learning, but you are building from pretty well nothing. The idea is to put something in place to get started, and start improving amount, coverage and quality. True you want to hit with a splash... but this is where working collaboratively as a team makes a world of difference.
That aside, doing something to a high standard is very achievable. Working to a plan with a decent strategy will still achieve far superior results to an ad hoc approach. Indeed, 9999/10000 times, an ad hoc approach is a complete waste of time, in that it gives highly disappointing results.
If you put the work in, not only do you improve what you can achieve significantly, you also give yourself the opportunity of having an end package you are proud of instead of having great music and everything else is amateur hour held together by sticky tape and wishful thinking
Hugely importantly, other artists are, in marketing terms, your competition... in that they are competing with you for the attention of listeners. You can either be that band who reaches 50 people, or 50,000 people. You can be that band that has a well rounded, professional standard product, or an off balance amateur product. You can be that band that has thought and worked it through, or a band who took a blind-folded swing and hoped for the best. You get the idea.
It isn't about reaching number one, or working yourself into the ground for something unattainable. It is about making the most of the time you do have available to make the most from your music you can reasonably make.
As to making money? The realistic position is nothing to do with getting rich, never mind getting rich quick. It's about making your money work for you, and putting things in place that give you the opportunity to recoup costs, with the hope of first breaking even and then funding the next releases and improving the standard of your work and it's possible reach.
There are so many things to take care of, true, but you don't need to do them all immediately. Hopefully with some help you can prioritise effectively, focus on the right things and with each release take strides forward that match a realistic expectation.
