Purchasing Services to convert photographs to raster images

[KLENKUS1 at VAXC.STEVENS-TECH.EDU]

Hello all,

Im looking into purchasing aerial photographs, and would 
like some information about companies that would 
rasterize the map.

Since this is also the first time I will be trying this
process is there any inherent problems that I should
know about?

Thanks for any information.
