This helped me start my business explosively, I hope it helps you!!
Start looking for bids with your local governments (city, county, state, country) and start calling the 'purchasing' department of each agency. Inquire on any new, upcoming janitorial service bids coming out 'to bid' If they say no--FIND OUT WHEN THEY WILL, and record that. Then call back around that date, and bid decidedly. Also, look into your local newspaper website WEEKLY and search in the legals for janitorial services coming out to bid. It is a religious undertaking, but highly profitable. You will need employees, insurances, equipment, supplies, income to pay the employees, references
, bid bonds, and certifications. Call your local SBA office, they will help you out. GOOD LUCK!!
