A good way to develop presentation skills is to participate on a local toastmasters group: https://www.toastmasters.org/, I have been participating regularly for a year and I found out that I've been improving my presentation skills.

Besides that, I like the idea of starting small: present something for your closer colleagues, then present for your company. Once you have a talk accepted and you find your lines of thought, rehearse: find interesting topics, present them for your closer colleagues and see if they can give you feedback, iterate on that feedback and you will have something great (I presented my first talk 5 times for my colleagues, and even on the last I found space for improvement).

I've wrote a blog post about it: http://blog.rlmflores.me/slides,/conference/2012/05/31/confe...
