ktw, the only thing I can think of is if you have phone book software available to you like like we have here in the US.
I've used a program called InfoUSA. You can download business' by your criteria and then export them to an excel program as a comma delimited file, or create a mailing list.
The InfoUSA software is a Sales lead generating program.
You can glean business names addresses and phone numbers.
Perhaps if you look for some business software that will help you increase your sales and contact lists you'll find one like it where you live.
Business.com Hoovers business information
Wow after searching around I couldn't find any software programs with all phone listings on them like there used to be, dosen't mean you can't but I couldn't. They all charge for their information per use.. sorry.
