Justin,
Come to the breakfast this sat and check out the bumpers I put together by ordering pre-cut pieces from NWTI. Honestly, I think as your first project, this is the way you should go. Why? For one thing, when you have a pre-designed and pre-cut kit arrive at your shop on a pallet, it's EXACTLY like playing Legos for adults.

. I kid you not, it's fun to puzzle it together. Once you actually start on this project, you won't be stopping because it's really fun to tack everything together and watch it slowly come together. Just drink some beer, and slowly build it. Slow is good, otherwise, you'll warp the s*** out things. You can tack the whole thing together in one weekend then spend as long as you want completing your weld. So, you'll be driving around with an unfinished bumper but who cares.
I've built bumpers for all my rigs and this was by far, the most fun I had. When you're not designing, cutting and noodling from scratch, the project moves faster and your desire to complete it stays at a high level, IMHO. I really hated cutting and cleaning up steel before tacking. While CAD'ing a bumper is fun, it also takes a long time and to be honest, there ain't too many ways to build a freaking bumper
Coastal Offroad and 4x4lab also provide bumper DIY kits for our rigs so check them out too. Mine is from NWTI out of WA state. My bumpers have my personal tweaks but having a good foundation to start with is really sweet. By doing a DIY kit, you'll be proud of your work and learn fabrication/welding at the same time. Your welding skills will improve exponentially on projects like these. Cost will be 1/3 less than a finished unit, typically.
