To make high-quality training videos, you need to have some hardware and software but most importantly – you need to have a vision regarding the output you are looking forward to.
If you invest 3000$ into pieces of equipment but no vision, you will have a hard time creating something of value.
I would strongly suggest you go through few online courses which are available for free on the internet to help you develop and understand your style of desired output after which you can put together pieces of hardware and software to make it into a reality.
Initially, you might face some troubles and quality issues, in that case, consult a professional who is/are engaged in producing it in a high-quality videos after which you can either outsource the work and focus on your strengths which in turn will give you much better return on investment.
