Hello,
I was just about to start writing that you have a romantic notion of the voluntary performance of the users here, when "emer" already expressed my thoughts very well.
the problem is that they only draw once we sign that we also want to build with them.
That is the bitter pill you have to swallow when you go to bed with a cheap provider; I definitely count DW among them.
But it's too risky for us not to know what we get before we sign.
A valid objection. You can only defuse this if you obtain serious offers; not every provider—especially not the reputable ones—wants your signature before they start working for you. But you must be willing to make compromises, because that is what building a house means! And above all, you must let go of the idea of implementing the concept of a look (DW) at all costs. By doing this, you are only standing in your own way; in this manner, building will never work out, and no creative architect will be able to meet your demands.
Best regards from the Rhineland
