What suggestions do you have for a creative promotional items?

Greetings and thank you for the invitation, 

Sir I dont think your question needs more clarification as in to which industry you need to the creative methods of advertisement, who your target market is, location, and what is your product that you're trying to promote. As you may promote a product creatively and uniquely on social media or technically.

Firstly, who is your audience?- so be specific including age group. 

Secondly, what are you trying to pitch?

Who are your clients and what problem are you facing in selling more of your product/services?

 It's a difficult question to answer without having more information.
