VoIPSwitch expert

Hi, we have rented a VoIPswitch server and we're having issues with DID management, getting errors in mysql database. The guy that rents us the server wants to get $40USD per one hour (terribly expensive), when we think this is its responsability, but well, it's fine. We think this is a nulled version of VoIPSwitch, but system works OK, just need someone that has a lot of experience with VoIPswitch and help us with this or other future issues. Please techs, this is not asterisk or freeswitch, this is windows and VoIPSwitch. Jyst experienced and affordable guys. If this goes OK we will do a lot of things in the future. Ah, just bid 1h, we will pay per every hour the price. Thanks.
