Create a great marketing copy for the launch of my up and coming webinars

The marketing brief states the aims of each webinar. I will use the copy to insert into
a)email marketing templates
b)Website promotion
c) direct webniar software registration templates

I need a marketing expert to review the essence of what I have writen to ensure the value and benefits are promoted and to increase the chance of the target market converting and registering .

I attach the marketing brief
Your own ideas and thoughts on what works would be really appreciated.
Further work available to the right marketing expert who can contribute to this marketing strategy.
