More budget options, than only Fixed price or hourly rate. I.e Charity.
What if you want to allow to create charity projects? Projects that do not have a budget but still needs to be created.
Sure you could create a fixed price budget with a price of 0.00, but I would like to let the user select "Charity" and then omit the price field.
The best solution would be if it was possible to define more budget options than only the fixed price and hourly rate.
