I think you could pull it off yourself. I'm also limited on time. I have finals coming up and plenty of assignments.Once you have the general idea of what is going to look like, go into your vectoring program or import raster images into publisher or any graphic software you have. Place them roughly where you want them in the image and draw the scene in around them. I placed my characters out in inkscape, exported it and printed it onto paper then just used a pencil and ruler to draw in the placement of objects and walls. Scanned that then vectored all the pieces.If you are able to draw then I highly advise looking at the show to reference their style. Some objects can be vectored directly from screenshots and tweaked if needed. What I go by is objects and scenes should be simple and as a rule of thumb objects don't have stroke lines (outlines). Work on that basis and you should be able to create objects that look like they could exists around show accurate pony vectors.I am sorry that I don't think I will have the time to directly help you out on this one. I do think it's a very good idea and I think you should take your time to get it just right. I tweak my work constantly. Never rush anything if you want it to be just right. I will never be able to know exactly what your perfect scene looks like in your head so I leave it up to you to make it a reality. I will do my best to support you if you want it.
