I am going into the Yellow Pages for 2009 - 2010. I have an advert going into the drain jetting unit (as we have a drain jetter) and I want to get a revenue stream that is independant from my contract works and I also have an advert going into the commercial cleaning section. I have never tried the Yellow Pages so it will be interesting to see the outcome, particularly on the drain jetting ad - as I see that for drain jetting people still use the yellow book.
There is no tried and tested equation on what works for getting commmercial works but one thing is for sure you need to be in the right place at the right time, even that can be manipulated to work in your favour.
Here's what I do
Offer your residential customers free cleaning for recommending you to their workplace, you get the contract they get free cleaning.
Have the best leaflet made you can afford, organise yourself a works portfolio to present and leave at companies, present yourself and your company with a good image, sign written vehicle, uniform, have a better business card than anyone elses - if I put my business card in a hat and you put yours mine would be the one that would get more interest because it is better. I have spent a lot of money on my cards and they work.
Your works portfolio is your potential clients view on you and your business, lots of photos, H & S, your services, contacts page. Ours mirrors our website. Get a website.
This one some might see as contentious - Go VAT registered, bigger companies like to use VAT registered suppliers, like a boys club, that you have reached a certain level!!!!
Be better than anyone else that is offering your services.
You can have all of that and your face might not appeal to the potential client, there might be something about you that they don't like - don't take it personally, ask them why they didn't use your service and learn from any mistakes.
keep at it and keep putting your details out there, the law of averages will dictate that sooner or later the more people know about your service, you will get the opportunities that you are looking for.
Good luck
