I am using tricks to promote my cleaning business. You can promote your site by searching different cleaning business on Google, like , carpet cleaning, dry cleaning , builders, ironing and ask for permission for putting your website link on their site. This type of advertisement will promote your site. You can try this with many cleaning site.

Agreed, cooperation between business should really be appreciated and welcomed by you, the business owner. Maybe you'll need to make a trade but it will work out for both of the business that are in the cooperation

That's how you put it a bit formally, maybe you have a friend in another company or something so that's how you'd get by, or not?

I didn't actually think of it before, is it a good idea I don't really know myself but I guess I'll take the advice to research about it
