l have a T-Shirt business on the 2nd floor of an office building, what are some ways that l can advertise from on a second floor. (Saying Look at me !!!! I am here on the second floor...lol)
The business that is under me is a hair salon...

Roar out the window about your business.
Put a sign outside your business saying T-Shirt business 2nd floor.
Grt a very large sheet. cut it into the shape of a T-Shirt, print your business name on it and hang it out ur window

You could hang a banner with bright colours to catch people is attention

you can put out a large banner outside the window or post poster saying you have a store up in the second floor or advertise about your store on the net, when where how.

Hehe. l would put a sign out by the road in front of the building, maybe above or below the business sign of the Business below you. l would try to put a billboard or sign of some sort on your half of the building up top in a position that would grab drivers and passerby is attention. You could also ask to hang a sign on the actual front door of the building as well. =) Good luck!

You can put a sign outside the door into the building giving a brief introduction to your company and highlighting deals or sales. This will give passersby the opportunity to see what you have to offer and where you are, especially since they can not just look into a window to see what is available.

best thing you can do is make friends..socialise a lot..let the world know of your existence..you can register yourself over the net..advertise on most visited sites..set up one day or two day shops at callcenters and other companies.think of a funky logo epicting about the store and the stuff that you sell there..such kindda ways and techniques can be used to advertise..i m like filled with FREE IdEaS..lemme know if you need morE...

Advertise with Rafikni.com. A new way to advertise check it out!!!!

First hang a sign

Then hand out business cards to local businesses.
what about having a walk thru, offer coffee and donuts and tee shirts to people who attend.

put a mascot outside that will direct traffic to store.

What kind of store is below you, can you make a deal with them.
Offer flyers in their store, hang up t-shirts in their store.
