how can I increase my productivity without breaking the bank to hit our goals

[Jason Malabute]

We go direct to owner campaign with apartment owners. We have talked to 36 decision makers and 2 appointments since October. 9 of the 36 DMs contacted was reached via text. We have sent 2420 texts. It takes in average 268.88 text messages to identify 1 dm via text (2420/9=268.88). 23 of the 36 DMs contacted was reached via calls. We have made 3435calls. It takes in average 149.34 calls to identify 1 dm via call (3435/23=149.34). 4 of the 36 DMs contacted was reached via emails. We make an average of 80 calls per day. If our appointment rate so far is 5.5% and close rate is conservatively projected at 5% we need 20 appointments to get one deal accepted. My problem is if we want hit our target income in one year we need to increase our calls from 80 to 300 calls a day. How can I do that without hiring more VAs until we are making $250-500k of revenue per employee. How can I accomplish this? I am looking at using A.I. or using mojo dialer so I can increase our calls per day. Does anybody any advice?

I have started looking at the following AI:

1. Conversica 
2. Saleswhale 
3. Exceed.ai 
4. Chorus.ai 

Has anyone used these before?
