New stores, make them popular!

I have recently launched three new niche stores, so I am looking for someone who knows what they are doing and can make the sites as popular as possible for as cheap as possible. Please tell me about your plans, experience, and why I should choose you for the job. I also need some SEO tips, so if you would like to consult me with that as well please let me know. PS: Don't care too much about the budget.
