I think you need to elaborate and provide what you've already accomplished

Look at the way vanilla TNT is handled.

First learn how to program in Java. Then learn how to install Forge (see tutorials). Then learn how to develop a mod in Forge (see tutorials). Then subclass BlockTNT, overriding what you want to be different. When you get stuck, learn how to post the proper details of your work and and the runtime log.

 

If you want to find somebody to make a mod for you, then you should probably post to another web site dedicated to mod requests. This forum is for mod programming help, and it expects you to have already done some study and some work, which you should evidence in your OP.
