At the moment it appears the problem is the p&c agents not getting paid enough to buy leads.
Thats a really bad assumption, not even sure how you got there, but it explains your thinking in a lot of ways.
The point is, for P&C leads, I can get telemarketed leads for $15-$20 very easily, whether I do them inhouse or hire it done. To pay more than that is almost foolish. The trick is to get it down to $10-$12 a lead so you can make more money, this can usually only be done by having the telemarketer in house.
The only way the value of a telemarketed lead really increases is to have it with a 'pain-point' of why they are willing to change or need a different coverage. This is why agents love referrals from mortgage brokers, there is a change in their life, making the lead extremely actionable. Its unfortunate, but simply saving people a few dollars doesn't really get them motivated to switch. Saving them a lot of dollars does, but its almost a myth you can save anything really that significant (yes, it does happen, but not like the ads make it sound).
Its also unfortunate that telemarketed leads tend not to be the higher value clients for P&C. Yes, some great leads, but I've never successfully telemarketed $1,000,000+ homeowners (they are abundant in the bay area).
Now, if you do commercial telemarketing, there is a lot more room to work with, but the expectations skyrocket.
