Please I need advice/ help

I am trying to migrate to Finland under the job route.

Sometime this year there was a news that Denmark wants skilled labour (electricians, plumbers, and welders). I know I need to get a job in Finland first before I can move so, I met this agent to knw how I can go about it. He proposes a payment of 150k and a scanned copy of my passport for job placement services in Finland, Poland, and Hungary. Within 90 days, they promise to secure a job, requiring an additional 4m upon success. The agent assures the job includes an employment letter, flight ticket, and 6 months' accommodation in Finland.

I have concerns:

1. Can anyone who has done it before shed light on this process and provide clarification?
2. Is this process legitimate? Committing to it involves significant risks like burning the bridges here.
3. Considering that I may reach there and there may be no job given that they are non English speaking countries, how can I cope? Any advice is appreciated.
