Icons for tabs and buttons for ERP Software needed

Hello,
for our ERP Software we need Icons (for buttons/tabs etc)
with the following specifications:
It must be
- intended for 64x64 size, but as svg vector file
- copyright free (we must own the copyright then)
- immediately recognized the function behind the icon, design is secondary
- if possible in the design of the screenshot attached
===============

There are a lot of icons (roughly around 80) and we ALREADY HAVE 90% of them.
Unfortunately we only have them in png file format.

YOUR JOB THEREFORE INCLUDES:
1. Take the existing png icons and transform them to svg vector files.
Download existing icons here: https://dl.dropboxusercontent.com/u/4435038/76%20icons.zip
2. Please design/create logos for these missing icons:

- edit
- print
- open in DMS
- copy to clipboard
- show stock history
- show stock history of all items
- show pic log file
- create intralogistic order
- show machine times
- copy
- print roll out list
- show picking log file
- show import log file
- print log file

We can also put 2 items next to each other:
Like: new document consists of new and documents.
So we can reuse the icons.
Therefore you can use the edit/print/copy symbol from the existing files.
If you have any questions, please get back to me.
