I previously had TFS developers downgrade TFS for me and it only took a couple hours, maybe three at the most. But that was with someone familiar with the distribution. I understand it will take longer with others, I even said this above.
I can handle everything except the source work.
Either way, it doesn't matter,
my offer is negotiable. My offer is based on the fact that the person
will resell copies of it, making it much less valuable. If the person who does this commits to supplying me (and only me) a single copy -- and never selling it again -- it will be worth more. But, there's no sure way to prove this.
Whether or not any of you "like" my offer doesn't matter. Obviously none of you are interested in completing this task, so what's the deal? Just like pointless conversation? You now have my reasoning for what my offer is. Don't like it? Leave. Nobody asked you for your opinion. And none of you seem to know what "negotiable" means.
