Decide ahead of time what areas that you want to work in
It will save you travel time and gas money between customers
Which means you will be able to schedule appointments closer together and either take on more customers or not work as many days or longer hours.
Start by printing some great business cards and get them into the hands of people in your target areas,
Any way that you can...coffee shop visits,door to door in offices,talk to people
The more you circulate yourself, the sooner you will fill that schedule
You can always try Craigslist as it's free,but will it specifically target where you want to work? trying to work everywhere is not something I would suggest.
Look into newspapers that are carried by stores and shops in your target area.Call them for rate information.Weekends are the best days to place ads
especially Sunday as people keep the Sunday editions longer than the others.
because of ads,the TV schedule...etc,etc.Also target advertising on days that the coupons are printed as all the ladies buy the newspaper that day for the coupons.
To begin with...schedule people around the hours that you are currently working,you will have to decide at what point you can afford to make the jump
out of your current position and into full time cleaning.
Hope this helps
