A model of gauge-mediated supersymmetry breaking is constructed in which the low-energy physics depends on a single dynamical scale. The strong coupling dynamics of gauge theories plays an important role, in particular through its effects on beta functions and through confinement. The model does not have distinct messenger and supersymmetry-breaking sectors. The scale of supersymmetry breaking is of the order of 10{endash}100 TeV, implying that the decay of the next-to-lightest superpartner into the gravitino is prompt. Superoblique corrections are enhanced. A Dirac fermion and one complex scalar, in a 10 or {ovr 10} of (global) SU(5), are predicted to be relatively light and to satisfy certain mass relations with the standard model squarks and sleptons. {copyright} {ital 1999} {ital The American Physical Society}
