Create a banner for a tech, female no-profit organization

Girls in Tech - Italy

Girls in Tech - Italy is the Italian chapter of Girls in Tech, a
no-profit organization that aims at empowering female
entrepreneurship
in the tech and startup world.

We target women of all ages, interested in technology and innovation.
Most of them have jobs in the tech sector and have either started
their own startup or work in one.

We are looking for a banner (851 x 315) which will be used as
background on our website and on our Facebook page.

You can see the image that we currently have on our website
http://www.girlsintech.it - it's a girl who wears headsets hiding her
face behind an iPad. This image combines two main topics of our
no-profit:
female + technology.

Now we are looking for something new, modern and more compelling. The
banner should express a sense of community, of empowerment, of
independence, technology and female entrepreneurship.

Style: yes, we do like pink in our logo and website, but we are not a
pink organization. We are for strong, independent, modern women who
are successful and ambitious in their jobs. The style of the banner
should express this.

It can either be a picture or an illustration. ILLUSTRATION PREFERRED.
It needs to go along
the current colors of the website.

Please no stock images. Please include our logo (attached). No extra
text in the banner please.

I also include an example of the current image and our current
Facebook cover photo.
