Don't quit your job. If you can't drop back to part time, and have to quit...find another part time job. Keep the part time job until all your equipment and carpet cleaning machines is paid for. I quit my part time job too soon in my early years.
When I realized that it wasn't making$$$$ what I wanted...I started credit carding and borrowing. Big mistake.
I don't know your local economy, and how well your'e marketing your new business, but if you're new to business management and marketing...don't quit your job!
It’s rare but I agree with this cat. Work your regular job, buy and pay off all equipment, build a marketing plan, implement it, work way up to high end paying clients and when your about to quit your job raise your prices and hold off for a little while longer. Then jump.
