say it with pictures, rough drafts, sketches, mock ups. Money talks as well, if you can convey to them that the utilization of your ideas will save them money in the long run… Many clients already have a very firm idea of what they want. I work in printing and can tell you that the customer does not always want the possible. There are a lot of things that printers find difficult and will charge a ton of extra $ and there are certain things that have to be fought by the printer because the client wont budge. Sometimes we just have to realize that the customer wants what they want and no amount of cajoling, insisting, or anything else can change that fool head…..good luck. I cannot tell you how many art peices I have done fo rpeople and have to make change after change after change…as long as we get paid, right!

Photoshop can import vector-based files, but it is not a vector program, it is a raster program. You'll want Adobe Illustrator. Photoshop will (should) allow you to choose size on import, and will retain the quality of the image if its a true vector image, but other than that it's going to end up in a raster format.
