You are probably undercharging. Not parent, but my WordPress specific work was either a flat fee for standard stuff (setting up a site, installing and configuring an existing theme, plugins, etc), or $50/hr for customization either through writing new plugins or adding functionality to an existing theme via PHP or CSS.
Laravel or other custom work starts at $125 for clients I'm expecting volume from or $150 for one off projects, again given in estimates as a flat fee for the project. If I expect something will take 8 hours to build, then I'm giving them a quote of $1200.
You can scaffold up a lot of CRUD stuff in Laravel in 8 hours.
Where do you find clients? My bread/butter is basically reddit - /r/forhire, Upwork is total shit, so I don't even login there anymore.
I'm wanting to potentially do some sort of hosting/support plan...and work on a site that has a ton more inbound marketing related articles on my biz. Then hire some offshore or jr devs or techs wanting to become devs to support the easy issues, I'll take care of the harder stuff, or hire some tier 2 people to do that... basically have something like $200/month for hosting, unlimited non-coding issues, change fonts, update settings, fix white screen of death, etc...w/ backups/malware scans/etc... -- the idea being get some recurring income.
Then I can up-sell people who need custom apps, full-design, etc... But before I can move into agency, I need solid/steady income. I had a bunch of imposter syndrome/depression but I'm depression free since August (therapy), and I've lost 90 pounds, and just have more energy, and I'm a lot more focused now, and just want to take freelancing to where I know it can go.
This business model is tried and true (WP Curve, GoWP). In fact GoWP has a great white label solution to handle all the maintenance you speak of at a fair cost. I used to combine their service with hosting on WP Engine (which included Sucuri for security) and have a ready made MRR model for WordPress.
