I work for a small company and I outsource plans to places like FedEX, Staples and such because I don't have access to a plotter.
Every reprographics center (ones that specialize in architectural plans - look up reprographics in your area) I've used knows how to do it and will do an excellent job. Kinkos (now FedEX Office) is hit and miss but I found one that knows what they are doing. I haven't had good luck with the other sources. I mostly use the Kinkos that I found because there service is outstanding. Again it varies with store to store.
If you look at their large plotters and it is a KIP, turn around and walk out. They have a heating problem and if the print is over 42" long it will start misprinting and leaving off print. OCE plotters do the best at large plans and I've printed 14' long scale plans without problems.
PDF is the smaller file but you can't import into AutoCAD (at least the older versions). You need a TIFF file for that but a PDF can be converted to a TIFF and TIFF files are very large.
Hope this helps. If you need a file converted from PDF to something else let me know and I can help.
