At least for me the progression was like this:
L1 - Sausage on grill
L2 - Meats on grill an getting the heat an timing right
L3 - Rubs and brines and grilled veggies
L4 - Baking bread and pizza
L5 - Serving a complete family dinner with different cuts of meat, fish, veggies and bread from one grill
Your best bet is through a company. If you have a reasonable job opportunity, familiarise yourself with the work visa and residency procedures. Your future employer will likely help you in the process.
However, the economy currently is tough also in the EU, so you’ll need to find a niche.
