I need a Professional looking logo for my new business

I would like a new logo for my business - Mount Everest Marketing Ltd. I do not want it to look cartoonish - but rather professional and trustworthy with an authoritative feel. The company with be a sales company that offers lead generation services etc to client/customers.

Ideally I would like a picture of Mount Everest as part of the logo somehow.

If interested, please tell me why you should win the job and send some other examples of your work. I will need the finished files to include a transparent version.

Thanks
