I would recommend, if there is one in your area, go to the local do it yourself workshop. These are hosted by bike shops and community organizations, have all the tools, and are often free or charge a nominal hourly fee. Way less cost than buying quality tools.

Also, there is almost always someone there to help you out and show you how to do something. This is better than YouTube.

Then, if you are still into the enterprise after a few months, buy quality tools one at a time, and remember you can always go back to the workshop for the unusual one. I still use community workshops for frame tools like bottom bracket cutters, eg. I need them once in a while but it is not worth the cost for me. And I still have the first set of Park cone wrenches i bought decades ago.

There is a saying here, "wer billig kauft, kauft zweimal." He who buys cheap, buys twice. You can over-do this idea (it is sacrilegious to suggest this for sure, but no one needs Campagnolo tools, or Park or VAR; there are other good options for the home wrench), but the principle is sound. Double the price of the cheapest option usually saves you money in the long term.
