  Existence of two solutions to a parametric singular quasi-linear elliptic
problem is proved. The equation is driven by the {\Phi}-Laplacian operator and
the reaction term can be non-monotone. The main tools employed are a local
minimum theorem and the Mountain Pass theorem, together with the truncation
technique. Global C^{1,{\tau}} regularity of solutions is also investigated,
chiefly via a priori estimates and perturbation techniques.
