Cpa networks. Bulk sms mailing?

Hello,
I've doing some heavy bulk sms mailing with one network and email submits. The conversion rates are quite low at about 5%. That's still a lot of money Also due to the nature of this business, I don't provide my tax info. If anyone knows of some cpa networks that can meet my criteria. Please pm with the details..
Serious inquiries only please, as I don't need any headaches.
Regards

I also do bulk sms, looking for a cpa network that can take the traffic

i'd also love to find out. thx!
