Model [Request] Payload Explosion

I've been dreading asking about this, to the point that I've even tried figuring out how to make the explosion myself, but I've never done any 3D modeling or animation work before and even using the tutorial I'm pretty clueless about this.

The picture shows what would needed to be blown up--a dam. It uses the dirty bomb cart from Hoodoo, so it explodes in front of the dam rather than colliding. My idea was that the bomb would do blast damage and blow a hole in the dam, with debris and stuff spilling out backwards, while water would pour out the front.

I don't need particle work or the water effects done--just the explosion animation. I feel pretty obnoxious asking for it but it's far beyond my level and area of expertise and I would really hate to have to abandon this map simply because of the explosion...If anyone would be so kind as to do it for me, I'll send the VMF file for Floodgates B1 in a private message. :I

It's no longer a problem, anyway--I abandoned my original explosion idea for something less cool/ambitious but more within the range of something I can pull off myself.

Glad I didn't bother anyone with it anyway, I'm probably going to be shelving this map anyway in spite of my best efforts to rework it.

Considering that I requested this over two months ago and it's only up here because MMaster necro'd it, I would've stopped anyone who had started making it at this point anyway.
