Change bibliography style and add references from url with latex

Hello,

please take a look at the two tasks and send me an offer:

1. All marked references should be moved from footnote to bibliography. Please check the pdf with the marked URLs. You have to add them in the correct format (including all necessary details, like the author, year, etc.) in the .bib file and display it in the bibliography. Please use for the new entries the access date that I have mentioned in the footnote (Abruf am …). If there is a time mentioned, please display the time in the entry too. Then you have to add the citation instead of the footnote number at the sentences in the text. Display the citation before the point at the end (see reference thesis for examples). Use in the common format (\citep with author and year, in brackets []). If there is not just the URL in the footnote (you can see a comment like "Vorgaben siehe URL", please don´t remove these footnotes. Instead, replace the URL with the citation and remove the access date. That means, please delete the string "(Abruf am XXXXXX)" completely and replace the URL with the citation like [Mustermann, 2020].
2. Please use german words for the bibliography style. It should be exactly like the reference thesis. You can try to use the babbel package with ngerman or a parameter for natbib to change the "and" to "und".

Please comment your code in a good way. There is no specific deadline, but a completion within the next few days will be very nice.

In case of questions, please let me know. We can also talk about this via Skype. Please only send an offer, when you have enough knowledge and experience to fulfill all requirements exactly. Quality is for me most important. If you see possible problems or other important tasks while working, please inform me.

Best regards

Corvin
