I need some Graphic Design

This year our business is celebrating our 25th Anniversary. We need a professional, creative, smart and fresh theme designing, for us to use across several items. We may be doing a '25 years, 25% off' idea, but there is nothing solidified yet. We need several things designing, with the 25-year theme incorporated... We send out branded biscuit tubes to customers - we need a new label designing for these. I can provide templates and past designs to work off. We need 2 e-shots designing - 1 to send out just before Christmas (maybe saying about how next year we celebrate our 25th year....look out for the promotion kind of thing) and 1 to send out when we come back in the new year. We will give information of what content to include in these - we just need you to come up with a professional design for these e-shots. We need a postcard/flyer designing for us to send to customers. We need an email signature designing, to incorporate the 25-year theme. There will need to be one for the first week or so, with a bit about the 25% off idea, and one that we can use for the rest of the year....The one for the rest of the year will be basically the same as the one used previously, just without the discount bit. And finally I need a design creating that we can use on both post-it notes and notepads. I can provide our company logo and stationary that we have, so this will give you an idea of what image we currently have. This project needs finishing by the end of November at the very latest.
