Let's start at the beginning.

Tell me where you get stuck today, and together we look at what is really needed. Out of that conversation comes what we build, and out of that a fixed price.

After a one-hour conversation you will know:

What we build: what it has to do, what it connects with and who works with it.
What it costs: a fixed price per phase, and the monthly amount to keep it running.
How it goes: in phases, and each phase you take into use on its own.

The conversation commits you to nothing, and you get an answer within a working day.
