Website UX Designs Required

I need a web designer to create UI PSD's for two products and a couple of websites.

First, there is an amendment to a website that has been mostly designed, but requires changes. I don't have the time to complete this so will need someone to complete for me.

Secondly is two products:

The products involved are both web applications. I need someone that has experience creating attractive user experiences for these applications. Both applications will need a "responsive" design as it needs to be used by people on desktop, tablet and phone. No coding required, we will handle that.

Application 1 will require the following within the design:
- Overall 'feel'
- Calendar
- Messages
- Lightbox bookings
- Search interface

Roughly 5-8 pages required for desktop, same again for 'mobile'. Basic sketched wireframes have already been created that will be sent to the winning bid.

Following this is the completion of the redesign of my company website. I have a design that I mocked up in Photoshop, I want it completing and made better please :)

Following that is Application 2, a messaging style app that will require a user interface not too dissimilar to Stack Overflow. More details to be released later.

There is also scope to work on a further four website designs for the winner, and I hope to have a great ongoing working relationship with that person.

Please note: Creativity and attention to detail are both necessary!
