Is there a way to have 2 groomsmen speak at the wedding?

I think you can do it however you want, both can give a speech or one speech and one toast like you said. Your day, do it how you want!

Hire a professional officiant.

Are you even sure he wants to do something? Your idea for the BM to do a speech and brother to do toast sounds good. Or they could both also do a speech. Don't over think it.

I agree, that sounds like a lot of speeches. Could BIL do a reading during the ceremony? And then just BM and MOH do the speeches?

Whoever wants to give a speech does. There are no rules. Your MOH may not feel comfortable speaking in from of an audience. Thats perfectly okk too. I would just tell them to keep them under 5 minutes for those who are doing them and limit it to 3.

Ive always seen them before dinner.

Do it how ever you want. They both can do a speech and toast or one do either or. What ever you guys want it your wedding.

If they both give speeches, please keep them to a time limit. My best friends wedding two of the groomsmen (no BM) gave speeches and it was the longest 5 minutes of my life.
