Artist Needed for designing lots of greeting Cards at $2 each

I am looking for an artist to design nice looking greeting cards for various occasions like New year, Valentines day, Birthdays etc for my website. The person must be able to deliver original work using original ideas and not copy anything from the net. Some design elements will be provided to the artist upon selection for the artworks. The cards to be designed should be in a variety of tones like humorous, lively, fresh, vibrant colors and light. The person must provide all the raw files upon completion and also give up all rights to the works . It will be a long time project for the suitable candidate. The contractor should be able to deliver the work on time. Should be very responsive and should reply fast on emails and chats. Should be able to start work as soon as possible.
