Is it possible to hire a professional webdev to check my amateur site?

I run a blog using a static site generator and HTML templates that I created myself [1], but I'm admittedly an amateur and don't have up-to-date knowledge on best practices or modern design patterns.

Is there a job site or webdev community where I can hire a professional web developer to check my work and patch whatever problems I've made for myself? Is there an agreed-upon way to do this or should I simply ask around?

Thanks for any and all advice.
