Well as your research suggests salary range greatly depends on experience and the company they work for. The range is 100,000 per month with little or no experience to 600,000 per month senior level / management. You can check different vacancies on Jobsora ng.jobsora.com/ and choose the most relevant for you.
It really depends what you can do and which software you're using. I would highly recommend to work with Autodesk software. Demands for employees with such skills is quite high. You can try to work with it using a licensed version of course. A cheap license you can buy from this Software Store online. Give it a try!
