Logo needed

I offer a number of generic login areas to my clients across 5 sites, and need a logo for these sites.

I intend to theme the sites in different colours – Blue; Purple; Black; Orange; Red.

Part of the domain has the word ‘Portal’ in, so I would like a logo that represents this. A Portal, doorway into another dimension. Think wormhole, door, worm hole inside the door. These are my ideas, but you may do a lot better!

The image will be quite small, 150width x 80high, although I may use it elsewhere, so it would be better if it was bigger but resizes well. I either need 5 logos that use the individual colour above, or a generic one with a transparent background that will go with all 5 colours.

Anything else you need to know, just raise a question.

It would be good if you could send at least one sample of your work that is relevant with your proposal, as it gives me an idea of the type of work you can produce.

Also, if you have an hourly that fits, let me know.
