Your profile says you are a non-EU national.

As such, you will not get a work visa for such unskilled work, because there are sufficient EU-nationals who can do such jobs (and have to be hired first).

Work visa are available mainly for highly skilled people, e.g. with a university degree and work experience in IT or similar fields.
