Hi,
There is always a market to meet a profession and there are multiple sources on the internet. However you must be aware of what will work best for you.
Since you did not stipulate what profession I can only give some suggestions.
a) Seek both theory and practical by subscribing to expert platforms like this and other ones that are accessible.
b) Seek to be qualified in your field by seeking reputable schools whether online or otherwise.
c) Ensure that the courses you are doing are certified, credible and recognized. (Alison, Coursera are just some of them.
d) If it is a career like designing, hairdressing, mechanic etc. try to get some hands on by being in the shop. (see how you can get that.
e) You tube always have suggestions and training on careers.
f) It would be good to find a mentor, a role model. This can be in a physical space.
g) Read a lot on the profession , the success stories, what are the failures etc. You need to know all you can about the field you are going into. Your interest must be peeked

Many professionals usually figure it out all by themselves, you don't have to go anywhere. But a career advice is always a bonus, you can try this website for example to get an advice. But the most important thing is for you to really dig in and find what you really want to do, YOU are the only one person that knows what you want best. Having an advice or someone to show you the way is also good.

You need to secure a professional business coach or mentor to help guide you through this process. A good quality person should be skilled in all areas.
