Easy grill / cook setup for camping

For the upcoming Dutch Bushscraft weekend mid September, I wanted to make a small grill / cook setup where my friends and I can prepare our food on between and after the workshops that are given there.
The sink is an old one, quite thick material, not one of those flimsy thin ones from these days.
I wanted to do it very low cost and with simple tools.
The result is better then I expected. The folding legs and removable pot hanging rack makes transport easy.
