Worth for finding referral partners?

I'm a merchant services and payment technology provider. Just getting back into using LinkedIn after many years and I'm very skeptical about its efficacy for what i want to accomplish. Looking to get my referral partner program in front of bookkeepers/accountants/CPAs. The current plan is to send 25 connection requests per day and 2 posts per week. In a few weeks (once I have more posts and connections) I'll start messaging them. I'll be happy if I can eventually get to 3-5 one-on-one conversations per week. 1. Do you see this working out? 2. Any suggestions?
