As the name of this forum indicates, this is not the place to ask for help to make a checker. The proper place is https://project-gc.com/forum/list?8 where the volunteers that help with checkers will see your message. Note also that the length or content of a cacher's logs are not a valid source of criteria for a challenge under the current guidelines for challenges, so unless you are asking for an already-existing challenge with these requirements, this is not a challenge that will get published.
