You can charge as much as people are willing to pay you.
Experience counts for nothing in my books, but maybe it does for clients hiring. There are developers here with 6 months Bubble experience that are better than developers with 5 years of experience. Years of experience is one of the last factors I look at on applications. Experience solving problems, though - that is valuable.
Write professionally for a start - communication is definitely in the top 3 skills that make a Bubble developer good. Communicate concisely, clearly and effectively with good grammar, in whatever language that is. Clients will trust you more.
The other thing you can do is have a special skill or niche that sets you apart. For our agency, it’s security. And it means that we can charge an effective rate (we don’t bill hourly) of well over $200 an hour, because we’re one of the only groups in the ecosystem that is capable of doing that For other developers that might be designing, I know some successful developers niche down into finance or healthcare, and those industries obviously tend to be higher paying.
As @Bubbleboy above shares, public contributions on forums are also a great way to get work. I hired two of our current developers (@nico.dicagno, @eliot1) from the Bubble Forum. The reason it’s so great is because if they’re not good, you can see that their responses are silly. But, if they’re good, you can see that they solve problems well and they communicate effectively because it’s all public. If everything they say is sensible and if they seem like a nice person to be around, then it’s an easy way to pre-vet someone.
Clients will also see that. A good portion of our clients come directly from the forum because when you’re in a bunch of threads, they stumble across you and they realize that you know what you’re talking about and might be able to help them.
Not everything you need to do has to directly win clients. Reputation isn’t as easily measurable as other methods of marketing like adverts, but it is so important, I have learned.
