[Help] How do I make a server using a custom modpack? [Help]

Okay, I just spent the last 5 days making this awesome mod pack for Tekkit, I then emailed each creator if I could use their mod, to my surprise almost all of them said yes. How ever, what I didn't take into consideration, is the fact I have no idea how to get this mod pack to work on a server, is there a fast way of doing this? I have always made a server using Vanilla and just put server mods on, never any client side mods... Can someone help? (I will not be giving my mod pack away until the server issue is resolved and I have got it working to the peak performance) Thanks for any information on this matter.
