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
Test the waters first.
Incidentally, I happen to own Lasered.com. If you like that domain / brand for a laser hair removal service, then you can lease it month-to-month with the option to buy later if the business takes off.
