I am going to start working on lead generation for local businesses. I plan to pay for a different number for each business I do lead generation for that has tracking whisper and records the calls. I plan to put ads up in search engines and have the number forwarded to the service provider and the call tracking information would help me know how much to charge the service provider for the leads.
What company do you recommend? I have seen one person here mention Twilio. I will look into that company. Does anyone else have any more recommendations? Looking for inexpensive but good.
