Hello alynnc25,
Here are some big picture steps you can take to help you with starting a bookstore.
1) MARKET RESEARCH
Primary: go to a nearby bookstore. Monitor how many customers it gets, how many customers buy there, what the bookstore offers besides books, shop layout (is it comfortable, does it look like a library?). Take notes on what it does well and what it lacks that you want to have in your own bookstore. Maybe if the bookstore is privately owned, you can have a candid conversation with the owner and ask him/her about the do's and don'ts of setting up a bookstore. Make sure you don't say you want to open one next door to his/hers.

Should do at least two in your neighborhood.
Secondary: Check the internet on the bookstore industry, is it growing, declining? Can the industry be broken down by niches? For example, if your neighborhood (within a 10 mile radius?) has a high percentage of fashion designers living there, then you may consider opening a bookstore that has a huge inventory of fashion mags/books that other bookstores don't stock. The US Consensus Bureau is a great resource for this.
2) BUSINESS PLANNING
You conclude that opening a bookstore is feasible through your research. Now you'll need to work out your finances. Do a 3-year projection on how much you can make and how much your costs will be. Calculate your initial investment. If it's more than the cash you have, then look to banks, friends, family, P2P lending, for the remaining balance.
3) EXECUTION
It's time to find a location, contact book distributors, find an interior designers to help with shop layout, buy furniture and fixtures and get a merchant account. The biggest part to this is negotiating a lease for your shop. Hopefully you can find a good real estate agent who can help.
4) MARKETING
You can do this in tandem with step 3. How will you let people know you're opening? Send emails to friends and ask them to send their friends and so on. Post an ad in a local newspaper? Or do nothing and let the people driving by notice your "Bookstore Opening Soon" banner?
I do not own a bookstore but these are the steps I would take. Again, there is no one better to speak to than a bookstore owner about this. It's a huge project so you should consider taking up partners.
Hope this helps. And if you decide to open one, I'd like to hear about your experience. Best of luck!
