Can I hire sales callers under individual contract without company registration?

Hello, I am a freelance content writer who recently moved towards marketing as AI has affected the content writing industry severely with a lack of projects. I have learned marketing and connected with people that can work with me on a freelance basis. Each of us has skills in different segments of marketing such as social media, website, AI art and more. However, none of our team has sales knowledge and therefore I need to hire a person that can cold call, present out services and booking appointments. I will be involved in collecting leads and providing the lists to them for cold calling as well as connect with the interested parties over video call to understand their issues, provide them with strategic actions, present an offer and close deals. I plan to start by providing the hired person with INR 10,000 payment per month along with 10% commission for every appointment/deal closing they achieve. My idea mainly is to get started and as soon as some finances start rolling in, I aim to register the business and invest in more automated solutions for lead generation and deal closing. I also have an area below my house where I plan to develop an office eventually once finances start coming in. Is my idea acceptable legally or do I need to implement any changes to the plan of action? Please take into account that my starting budget is significantly low right now so I have limited options.
