Lake County is accepting sealed proposals from experienced and qualified vendors seeking to establish a contract to provide services for Z/VM Programming Support, Z/VSE Support and Computer Operations for the Lake County Information Technology Department. Proposers should detail a model in which they will provide these services, including proposed staffing and work arrangements (for example, on-site versus off-site/remote). Proposers will need to provide on-site coverage, as discussed in detail below; however, they may use a combination of on-site and off-site resources to fulfill all of the requirements detailed below.
