Design Christmas Card Image

I need 4 images made for greeting cards, 3 for christmas and 1 for easter. As you can see, i am not much of an artist, so have done up stick figure versions of what i am after. these are very basic and you should fill in the gaps with themed items. I have attached the last 3 christmas and 2 easter cards as well as a normal cartoon image of me. plus my business icon and images of my car. Cards should be dimensions of 2100x1500 (landscape) or similar but with same ratio. the 3mm around the edges should be a bit plan and not have much detail (except the bottom), so that the bleed on the print out does not cut anything detailed. The cards are: 1. Christmas - on the road. This card is an image of my signwritten car (images attached) - with cartoon me leaning out of the window waving (wearing santa suit). general background is clouds, sun etc as per the xmas card (2012), and some presents around the background. remember its summer in NZ at Christmas. 2. Christmas - in the pool this is me in the pool, floating on a lilo(? floaty thing), with drink in my hand. wearing half a christmas outfit like in christmas card 2012, with the santa suit items strewn around the image as per the other card. a cat, some presents, a barbequeue around the pool area. DUX icon on an item floating in the pool (ball or something). 3. Christmas - BBQ Me cooking at a barbequeue, holding a drink, sun and clouds in teh background, and presents, trees etc. i will be in a santa suit, but not the whole one, barefoot, shortsleeves etc. DUX Icon on the side of the BBQ. 4. Easter This is a portrait card, me in a normal suit, with rabbit ears, holding an umbrella. all around the feet is a build up of easter eggs, and there are eggs falling from teh sky. the DUX Icon is on the umbrella. I would like this finished in Jpg, gif or png and AI, or PSD file. Any questions let me know. i can supply a .AI file for the cartoon of me etc. If you have any ideas of sample images you can send me with bid, that will help.
