I need hundreds of digital paper designs

I'm looking for a graphic designer to design hundreds of digital paper designs. I have attached an example of digital papers we are already currently selling. We already have designers but require 1 new designer to work for us permanently. Your quality of work must be the same or better than the attached designs. I will require many different types of designs like the attached. I will be reselling the digital papers and therefore will require full ownership of the designs. I will also require the job to be kept 100% private. This would be a permanent job as we will require continuous work after this job is complete. I have currently set my budget at £2.00 (GBP) per pack (each pack includes 10 papers). I will require approximately 50 packs in total. This is just to begin with and then I will go on to order more.
