I have a new business and plan on running a marketing campaign for 6 months is this too long- I will not promote

Hey guys! I have a new business (I am going to be selling wigs), I am really new to this industry and don’t have a social media presence. I plan on running a 6 month campaign for the business. The aim of the game is to gain attraction and build a solid loyal cult like-community. My wigs will be priced at £500-800 for a 50% markup. Seeing as we are just starting. I plan on pitching my idea to a female run venture capitalist firm, I seek £15,000 for a 10% stake in the business. However, if this doesn’t see through I will be using my own money which isn’t very much. Hence the reason for the campaign, to build a community authentically and organically rather than pushing something in someone’s face. My campaign will include me making videos sourcing the hair and showing the process on how the hair is acquired and how the wigs are crafted/ made. Also will be showing a behind the scenes of me as a new hairstylist. We plan on doing this to build trust. Feel free to ask me more about how I plan on marketing, I just wanted to keep it brief for the post. My question is, is 6 months too long? Thank you so much in advance, I can’t wait to hear your feedback
