How to make my own USA Topo basemap.

I have GIS users in a field office who tell me that they have to avoid using ESRI basemaps because their internet connection is so slow.  I already offer them image services  of some air photo sets with ArcServer 10.3.1 which sort of substitutes for ESRI's imagery base maps.   I thought, hey, I have a set of USGS quads for our state (Washington) and have ArcServer 10.3.1 running in the office, maybe I can create my own background map of topos for these users. I launched an image service of a mosaic of a small area of quads.  It looks good at scales 1:24000 and larger, but starts to look crappy zoomed out much more than that.  What's a source for 100k and 250k USGS topos for Washington State?  Should my approach be to publish as a map service to handle the scale dependencies,  so the service will switch to the appropriate map for the users map frame?

Here is another good link to download data from, but sometimes the data are not free from this site.
