cpanel subdomain creation scipt

Hi, My servers or reseller accounts run on linux and using WHM/Cpanel for control panel. I need to create in bulk quite a lot of subdomains in whm or Cpanel. I would give a flatfile for feed (1 subdomain name per row) and the script should automatically do those subdomains/domains as Cpanel would do when doing by hand. This script would only be installed on one server/reseller acct. and work over that entire server or over anyone i choose. So the important part is, I wanna administer those in Cpanel after they are created, so the script should do the same as Cpanel does but with the difference, that I can give a feed of a file (or variable if easier) that will be used for creating those subdomains. P.S. plz fill in PMB a contact info to you so we can check whether you know what I exactly want before I accept your bid. this is a one time project/script - on long term project. thanks
