Gaurav,
Eloqua provides sample nurtures out of the box - are you not able to access those? If not, I'd contact your AM to see if you can get them loaded to your org. Otherwise, there are plenty of nurture-related posts within Topliners - from the EE presentations to others - plus Eloqua's Grande Guides, Power Hours and other resources to help support your research.
Briefly, in my experience, you'll want to answer some questions before you begin building a nurture, such as setting the timing - "what is the ramp up time needed for the event," "who is our audience, how hard is it to get time on their calendars," will the audience need to book travel," etc... Those types of questions will help you determine your nurture start date, which should then inform you as to how many touches you'll need to consider. Also, consider your audience - are they net new, existing customers, a mix of both, partners, where are they located, do you have personas to leverage, etc... - this will help to inform you as to the number of touches and the messaging as well.
I guess what I'm trying to share is that the actual nurture "sample" itself is the end results of the planning I've mentioned above, although I've not hit all the key drivers. Do you have all this planning in place? If so, and would like to share it, you may get more meaningful feedback.
Best,
Kristin
