dns expert

I need a dns expert to help me setup and change some settings I got very small hosting company, and want to professionalize some stuff, like dns . I got problem than my provider works with separate dns server, i think just to monitor all, because got 11 servers, all domains must be added into that dns server. than one day i forgot to add, and the domain showed up anyway, This is server with clients, and total of 400 domains, which is good, i not had to add them one by one My suggestions because i created own dns on the server, and bind was working fine. Because of this dns server my hosting company is not fully automated. I use WHMSC as panel, and users can create account, buy stuff, the domain is added into the server attached, but i need to add the stuff manually again into that dns server. Which also gives a lot of errors while tsting dns health. I need to have perfect dns settings for my clients, and also option to have dns failover for mail for example. Right now i only can add one x record Another big problem is reverse dns,imposible to do without asking my provider. PTR is in my dns server,, but it will not work when added.
