It seems like a great book and offers a lot of creative advice for successful bartering of services. The book is available on Amazon, you can order it here.
The authors, Karen Hoffman and Shera Dalin, offer some sound tips on bartering:
Listen. Keep your ears open for what people need or want. Even if they haven't considered bartering, take a chance and ask them.
Be creative. Don't limit yourself to objects. Consider bartering tutoring, housecleaning, haircutting and other skills.
Make a list. Write down potential barters. When an opportunity arises, you'll be ready.
Be proactive. Create your own opportunities. Organize a neighborhood barter party or save money on sitters by creating a babysitting co-op.
Persevere. If someone declines your offer or a deal falls through, don't give up. Wait and try again — circumstances and attitudes can change.
Think big. The authors write of one couple who bartered for their first home by offering to make all the needed repairs themselves in exchange for living in it rent-free. After six months of hard work, they had saved enough money for the down payment.
