As we have several new clients, I think the workshops will be beneficial in helping the team create broadcast promotions to increase sales of products.
콤마뒤에 동사가 think, will be, create 3개씩이나 되요... 어떻게해서 이렇게 되는거죠?

주절에서 전체의 동사는 think이고, think가 이끄는 목적절에서의 동사가 will be 입니다.
(목적어절을 이끄는 that은 생략되어 있다고 보시면 돼요.)
그리고 in helping이라는 전치사구에서 help가 준사역동사여서 원형부정사인 create가 온거에요~
음, 눈에 보이게 묶자면
As we have several new clients, / I think [(that) the workshops / will be beneficial <in helping / the team / create broadcast promotions to increase sales of products.>]
이 정도가 되겠네요.
