I can write custom software for you. Usually you can find what you want for sale in the store. When you can, that is the only sensible thing to do.
Sometimes there is just nothing like what you need. I can produce the package you need.
Often you can buy most of the pieces but there are a few little connecting
parts you just can't find. I can write those for you.
