Tyvek Running Numbers/Bibs

[lost in espace]

My company is paying a fair whack for running numbers to be printed by various companies, and there is also the matter of slowish delivery.

Looking at doing this in house, anyone have any contacts or suggestions for purchasing Tyvek and printing?

I am getting some samples sent to me, ink jet is fine apparently although I have a nice gel jet which I may use.

Next question, what software can I design the bibs on and include number ranges?
