Should I invest 100,000 + in new business to make it look good and be professionally acceptable, or should I invest the minimum just to test the market but then I may get hit by bad reviews for my service. The Service I intend to offer is laser hair removal
Can't you find a way to partner with qualified clinics who have capacity, and then market to clients who would want to pay for one? After all, even if you go all in, you're in the business of selling/marketing the products, not servicing the products. You may as well test that first before you commit further (buying out businesses, increasing capacities, etc.).
