A few thoughts:
Anytime you bring a new product to market, you need to identify that market.
As has already been pointed out, elite travel ball is not your market.
TB coaches, players, and parents are inundated with widgets that claim to improve anything and everything.
It's all been tried and tested, and with respect to hitting, we always come back to two methods:
Tee work and live pitching.
Your ball on a... err, "1/4' diamond braided nylon rope, 2 feet of personalized heavy duty shock cord, Diamond fastpitch softballs, custom ordered comfortable foam grip with a safe wrist strap that is fused into the handle and rope itself , and all conections double crimped with heavy duty rings as well as covered with two layers of adhesive filled heat shrink tubing", isn't going to revolutionize training at the elite level.
Your market, again already pointed out, is the Big 5 type chains that sell beginner-type training equipment.
Yes, you should try to get some endorsements. Start with your local LL, HS coaches, etc. Build from there. Once you have a slew of ringing endorsements, then try to sell it through a sporting good store / chain. That is where your volume sales will come from (if anywhere). And volume is the name of the game with type widget.
The name "Bumblebee" has "beginner" connotations. Little kids will relate to "Bumblebee". TB players relate to "Rockettech" and "Techzilla". Which makes "Bumblebee" perfect for your ideal market.
Is the nylon rope really 1/4 foot? Simple errors cheapen your "pitch", and your product.
Getting this product to market ( a real market) is going to take time. And money. But if you do it right, you will make your money back, and probably return a nice profit for years to come. If you have a patent. If you don't have a patent, a larger company will "adopt" your product, patent it, and shut you out.
I could go on, but then I'd have to charge you hefty consultation fees.
Oh, one last freebie. On your website, you prominently feature 3 photos of "instructors" with "little kids". Your product is nowhere to be seen in any of the 3 photos. Which in my book makes the count 3-0. Capice?
