Kannel expert

I am looking for a Kannel expert, preferably with experience on Playsms, mysql, and GSM modems. We have an implementation with Playsms and kannel, works fine up to 20 sms, recently we test it with 600 sms, sent about 15 and then it got stuck, we think it was because of regulations from the operators, so we need to learn how to set messages sending with intervals of 50 seconds more or less. Also, we have encountered and other problem that we can not solve, when the server reboots, we have to start Kannel manually, it does not start at boot, so we need to learn how to do that, I run htop and I can see a process of kanel running, but when I check the status URL, is dead, so we we need to know how to fix that. Also, we need to know how to work with several gsm modems, and how to work with modems like wavecom 8 sim modems. And final we need to test it with 500 sms.
