The Universe became fully reionized, and observable optically, at a time corresponding
to redshift z ~ 6.5, so it is only by studying the HI and molecular
absorption lines against higher-redshift, radio-loud sources that one can hope to
make detailed studies of the earliest stages of galaxy formation. At present no targets
for such studies are known. In these proceedings we describe a survey which
is underway to find radio-loud quasars at z > 6.5, and present broad-band SEDs
of our most promising candidates.
