I find this part objectionable:
When the job is completed and tested it will be open sourced, GPLV2, copyright will be assigned to 'The Modular Company BV' in the Netherlands.
If this is GPLed, then it shouldn't matter much who holds the copyright. If you want the copyright, then it's not much of a sign of your belief in open source.
Ideally you'd accept MIT licensed code.
