I’d recommend searching the forum to find mentors and/or adding a post saying you’re looking for a freelancer who can help. Each of the Bubblers that run Bubble training classes are typically really good, and they all seem to market themselves in the forum.
In my experience, it’s cheaper to pay more for a really good Bubble developer than it is to spend longer to do the same work with an average one. Good ones typically charge $75-125/hr, give or take. Additionally, there are many developers that are cheaper (likely starting around $10/hr) but if you’re going to do most of the work, then you’d want someone really good who can get the project architected and started in the right direction (e.g., ~4 hours) and then someone who can help with the parts you can’t solve. The cheaper ones often aren’t very good at either of those types of tasks, in my experience.
