AirlineDecal Sheets

I need A4 size sheets designed for some basic elements of decal sheets that I can then print onto decal paper to help me building model aircraft. Initially there will be a few sheets which are just combinations of aircraft windows, cockpit windows and aircraft doors. So once the basic elements are created they can be copied to complete new series. I can supply source material which shows similar projects, and gives the proportions and sizes of the elements and their relationship to each other. AS such I would expect each sheet to take less than an hour to make. If I can find a good quality, precise freelancer I will likely move onto more complex, one off work. The work will be initially to help me with my projects but I might decide to sell of spare sheets. Copyright would remain with me.
