I have helped hundreds of early stage startups and businesses, and would be happy to provide you with an informed answer. But, in order to do so, please provide additional information.
What is the field of the business?
Is it a new or an existing business?
Do you have a small/medium/large budget?
Do you have knowledge in online marketing/social media or would you need someone to do this for you?
I'm happy to have a short conversation to point you in the right direction. the first few minutes will be free of charge so that we can first better understand your needs.
Best of luck
