Hi
I just read your project description and it seems something that I could help you to make it successful.
I have the experience of setting up a marketing strategy with combined platforms like Facebook, Linkedin, Adwords or something else depends on the niche and the goal.
Actually I worked in a very similar project before where I combined different type of ads (Facebook, Adwords, Emailing, etc) to get more leads, and it was pretty successful!
Best Regards
