Ok, I'll give you a hint. 1.B c7-e5
Will the pawn promote?
If so, on which square?
If so, what should it (not) become?
Are all the bishops important?
Is zugzwang a motive?
Is there only one solution?
Answering one (or more if necessary) of those questions would be a hint. Just giving away the first move doesn't feel right.

I have a question : what is with all the dang bishops. If I had the oppertunity in a game to promote three pawns the last thing I would get is three bishops. I tell you what, I would have ended that game awhile ago with a couple queens. 😀
This puzzle would certainly be categorized as one of those. Not only are there so many bishops, but somehow they all ended up on the same color as well. Pretty unlikely, but still interesting.
I still don't see how there is a forced win for this puzzle. I see how it could be won, but it seems to require some cooperation on Black's part.

Surely you meant 4.Bbe5! a3 5.Kc3 Ka1: 6.Kb3+ Kb1 7.Ba1 a2 8.Kc3 followed by checkmate as we know it?

It's a draw. There is no possible mating pattern with no matter how much single-color-squared bishops.

Just kidding. But kbaumen is right, there is no way to mate. If black plays it perfectly. Explain your solution so that someone here can explain why you're wrong.Then if you still want to give me that $1,000..... 🙂

This is how the end of your second solution to the puzzle looks:
Is not checkmate 'cause King still has a2. And if white doesn't move after king a2 then stalemate.
