Logo for Marketing Consulting business

After years of success as a marketing manager at various IT companies, I am starting my own consulting business to assist companies make strategic and profitable marketing decisions in the global financial crisis.
Help me sell my consultancy by designing a memorable, eye catching, modern & clean logo that will be used across all my collateral and stationary as well as online.
I have used 99 designs to design my wedding logo & had incredible success. Now it is time to use it for my business life.

GSC

A logo that is memorable, easy to read and clear as well as printable on a variety of mediums.

The logo itself should consist of 3 levels

GSC

Gina Samuels Consulting

Marketing - Communications - Events (tagline)

I would like 2 versions of the logo, one with GSC and Marketing Communications Events beneath it and one other logo with GSC and Gina Samuels Consulting embedded in it (in smaller writing) with Marketing-Communcations - Events underneath it. I will then select which is better.

The logo itself needs to be very recognisable yet clean, modern and sharp.

No script, swirls or anything old worldly. I am a modern marketeer with a strong focus on Return on Investment and a deep respect for marketing fuelling the sales process. I am a serious marketeer who drives results (not just pretty collateral)

This logo will be used across my whole business including:

business cards

stationary

collateral

giveaways

embroidered on apparel

website and online pages

print advertising

Therefore the logo needs to be clear and readable.

- A logo that is memorable
- The 3 letters to be incorporated into a design so it looks like a logo rather than just 3 letters
- The tag line to be clear yet GSC remain obvious that it is the company name
- A modern looking logo that represents me, my postive attitude and will still look modern in 5 years

- No script, swirls or old world font
- No predictable 'marketing graphics' like links of a chain or pyramids
- Not a logo that is hard to print or read
