I'm a big believer in leveraging your connections though. The best hires I've made came from referrals. Check LinkedIn for connections and introductions or use Clarity to call connected folks and pick their brain!

Yes. You don't have to have a location to have reviews displayed as a rich snippet in search results. There are a number of resources you can use. Schema.org can help you learn how to markup your HTML so that Reviews are labeled properly.

This site makes it even easier by populating the code for you: http://schema-creator.org/review.php

Once you have your code, test it with Google here: http://www.google.com/webmasters/tools/richsnippets

Keep in mind that even if your code is accurate, Google might not display the snippet in search.

Network. Talk to everyone you meet and know about what you're doing. You'll be surprised by how many folks know someone in need. Have a clear message about the value you'll bring to your clients. Be confident in that value. Consider offering your services for free or at a discounted rate to start with if the client gives you a recommendation and lets you use them as a testimonial. Word of mouth can be an enormous way to build your business and you can always incentivize client acquisition through existing clients (give them a discount or free service or a gift card for bringing you a referral). Network with other consultants in your area as well. They may have an excess of leads that they can point towards you and they'd be even more happy to do so if you give them a commission. Start local, talk to a lot of professionals, and do great work. The leads will come! I've grown my business to a million in revenue and eleven team members purely through reputation, referrals, and visibility. Best of luck.
