If you want to learn frontend web development for instance, bootcamp curriculum is inferior to simply reading Mozilla Developer Network.

Paying for mentorship itself in programming is over-rated:

Question about career advice? Programming Discussions Discord server, /r/cscareerquestions, Discord servers with #career-advice channels.

Stuck on a topic you're trying to learn and need help? /r/learnprogramming, one of the numerous Discord or Slack servers available.

Code not working? StackOverflow, Reddit, Discord, Slack.

Advice on improving code, best practices for software development? Code review StackExchange, software engineering StackExchange, Discord severs, et cetera.

Practice problems? Leetcode, HackerRank, other challenge sites.

A web development bootcamp is not going to teach you anything there is not a better resource already available for.

When many people (I'm speaking very generally here, not talking about you) talk about mentors in programming, they want someone to hold their hand and spoonfeed them information. If one wants to be pointed into the right direction, there are ample places for that.
