Graphics and Icons to a certain style

I had someone help out with a set of icons which are completed, but the designer can no longer work on continuing the project. I am in need of additional icons and some graphics that would have a similar style. I am attaching the 3 out of the 6 icons that were made to give a sense of direction and style I'm looking for. These were provided as .ai files so we have those for reference as well. I'm looking to create about 3-6 more icons and a graphic that will be used for a "welcome page" of an application dashboard. This graphic will resemble a similar style but will not be an icon and will be a little more in depth to what it will be signifying.

Here is an idea of what needs to be here: https://dribbble.com/shots/6509474-Application-Process. It's almost like we need 3 scenes in one graphic

But each should look more than just an icon. I guess more going on like these:

But we don't want any "people" in them.

This has to be done as soon as possible so please let me know of your schedule and timeline. I can provide more information to the appropriate candidate. I will need to see portfolio or examples. Prefer if you have similar icon design experience compared to the ones that I attached. Please no generic proposals as those will be declined.
