Hand Drawn Network Diagram (icons) for Web and Proposals

Computer

I design and deploy Citrix virtual desktop networks for customers. I am working on a new service with an online "shopping cart" to purchase fixed rate projects to deliver desktops to remote users.

I want a set of consistent network diagram icons for web and internal document use and access to a designer for future needs.

Please see the attached image. I only need icons with transparent backgrounds and perhaps a palate of colors (pretty monochrome, blues, greys, and maybe a couple bright callout colors - I'll use for boxes, dividers, arrows etc).

Every design category has flexible pricing for all budgets. Icon or button starts at HK$1,599.
