From time to time, I get the question: "How we can find business opportunities?" or "Do you have a genuine campaign for me?".
My answer is every time the same:
I'm not a campaign broker. It is easy to wait for a campaign broker rings you up and ask if you like to make some work for one of his customers. This is the way, where you get scammed too.
You own a call center and you have agents, which are only partly busy with work. Why do you not use your agents, which are not busy, for selling and promoting your own center? In such a case you need not pay a high broker fee, because your own agents are cheaper working.
Use the Internet and search at the job platforms like craigslist, elance, indeed, etc. Sell your own services by calling such companies, which are searching for telemarketers. Promote your own services by putting advertisments at such platforms. All that is called marketing. You are doing this for your customers too, do you not trust your own services? Don't wait until the brokers are knocking at your door.
