Corporate logo needed for tourist sightseeing company

Visitor Sightseeing

We are looking for a logo to help tidy up the current company image. We are a small company that resell tourist packages for larger agents.

Normally students or school parties come and stay at the large hotels nearby and buy our tourist packages. The packages are all london based. the audience are tourists, mainly from europe and local population who are just coming down to london on holiday.

Our current site looks like this

http://www.visitorsightseeing.co.uk/

The logo needs to look smart and corporate as the hotels adjoining us are imperialhotels.co.uk, and they have an old fashioned brand. However, this company needs to look young and fresh, yet formal so school teachers can trust us.

1 - Nothing humours or too playful so it doesnt look cheap
2- Nothing over the top, dont want to look too exclusive, just smart and official
3- the type face needs to be clear and legible

The site link shows what we are now, and shows how terrible and old fashioned it is.

feel free to play around with colours and typefaces, not locked onto one thing

The files we will require are:
Print file format - .ai (CMYK)
Web file format - .jpg and layered .psd (RGB)

Please avoid stock/clip art please
