Dear Ahmed,
It depends on type of business which you are working and trying to sell your products or sevices and it needs more details about your business.
But if I want to say generally, you can use news paper cuttings , tender notices, cold calling , net marketing , attending exhibitions related to your business and holding conferences ....
I wish you all the best.
