You really need to be working with an immigration lawyer if you want help with the TRP or have more questions. We cannot advise you any further than we already have.
Anyone who is asking you to pay 30K in exchange for a job is trying to scam you.
Generally speaking, it's next to impossible to secure a job offer since employers are not willing to go through the LMIA process which is required to hire you and allow you to apply for a work permit. The LMIA process is long (typically 4-6 months), expensive for the employer and has no guarantee of approval. It requires the employer to advertise the job for at least a month first to prove no Canadian could be hire for the role. There is no list of companies that hires foreign workers. If you want to try applying for jobs, you would apply through normal job sites such as linkedin and hope you find an employer willing to go through the process.
