Some initial thoughts and I've no doubt there are people with more experience than me in this. I'm not familiar with the business you are in. I'am assuming you have a web presence as you're using Google.
- Does your target market use Google to look for your services or how do they find you? Word of mouth, paper publications, industry groups, etc. Google may or may not be your primary driver of new customers.
- Is there a strong Call to Action on your website/landing page when prospects come in from Google?
- Are your past and/or current clients the right target market or has that shifted?
- Do you have/maintain or can access a list of past/existing clients to do some phone or email marketing? If you're not getting new business, you may have the time to phone previous clients. You'll need some sort of key message/offer before making those calls.
- With regards to the previous comment, I agree that cash/cash flow is probably needed before you can invest in other marketing or sales activities.
- If you do direct sales, is an option to look at a junior, but very hungry sales person to work off commission and make calls to try and establish new business or open some doors for you to then close the deal (don't know if this is appropriate to the business).
