There is no such thing as "quick money" so get that out of your head immediately. Think long term, think growth, think about niche positioning, think about looking at how to save money by being more efficient. Think about raising quality and raising prices accordingly.
Any effective marketing is a long term process. Its about establishing your identity, building on that identity and continuously repeating that identity to the customer/public through both internal and external marketing.
Internal marketing consists of store ambiance (layout, colors, music, etc.), product offerings, product quality, customer service, type of cups used, knowledge of coffee/tea/espresso, etc., interior signage, and more.
External marketing includes print ads, logo, exterior signage, and any additional PR such as working with local charities, using local dairy products, etc.
That being said:
From my personal experience:
Concentrate on your espresso and or coffee (and please no drip, unless it's by the cup (aka Melitta filter)). Immediately establish yourself as the best in your area by the quality of your cup. This must actually be better, not just wishful thinking. [Source better beans, use better brewing methods, make every cup important]
Ask yourself, "How can I make it better?" (updosing, downdosing, different temperature, different extraction time, etc.) Practice. Experiment. Repeat.
Become the local expert, be nationally recognized by your peers and prove it by the result in the cup.
Be patient. Continue to learn new techniques, tweak old ones, and/or become more consistent with what you're doing. People will go out of their way (drive, fly, plan road trip, move to your area... just to have your coffee and/or espresso. We regularly have people go out of their way to come here, and we've still managed to operate below the radar. WOM does wonders, but you have to deliver every time, and sometimes that means pi$$ing some people off.... (No soy cappa, no lungo shots, no cream or sugar in the press to order coffee....) but it will endear you to countless of others. Your integrity is reflected by the compromises you are willing to make, a compromise in quality is a compromise in integrity and it will show. Ask yourself, "Do I want to create a lasting legacy? or Do I want to be just another coffee shop?"
Sales are relative to your location, size, staff, business saavy (running a tight ship), and in the end the 'Bottom Line'.
By doing the above we've increased sales 350% since 2005, and are approaching our third year anniversary. We're relatively small, but we've been profitable since month 3, and have been able to triple payments on both our start-up loans this past year. Focus on the coffee and the sales will come, doing several charity events a year is also a good idea to build a relationship with the community, to create 'goodwill', and to get people who care about a similar cause, charity, ideal, to come and have your wonderful beverages.
Don't focus on the money. Focus on the coffee and how to improve quality and improve efficiency in ALL areas of your operation.
My cent.
