Looking for a mentor and possible partner

I’m a self-taught Front-End Developer that is trying to shift fully to freelance and I’m looking for a mentor and possible partner for some projects.

I’ve worked as a junior front-end developer for almost 2 years for a start-up where I didn’t have too much guidance or code reviews, I had full ownership of the projects that I’ve worked on mostly marketing/presentation websites so I don’t know if I’m working on industries standards. I started to learn by myself vue.js and nuxt.js and build some projects with them for some clients. I’m a bit lost because I want to shift my attention to freelancing and I don’t know how much to charge on projects, I don’t have procedures in place and stuff like that but I have a network of clients that were happy with my work, designers that want to work with me so I could say that I have a few clients. I also lost a few possible clients because I wasn’t sure If I can do the work and I don’t want that to happen again so here’s where I need a partner to work with.

What do I need from my mentor?

To answer some questions about freelancing, to help me put in place a tech-stack(Preferably a JAMStack) and some code reviews.

What I can offer?

Some money, we can agree on a monthly pay or something. And possibly some projects from time to time.
