Arabic romanization / transliteration to IJMES standard

I'm looking for help romanizing/transliterating Arabic-language footnotes in an academic book about the history of US-Saudi relations. These footnotes are currently transliterated into the Latin alphabet informally, without using any diacritical marks.

I’d like to convert them to the system used by the International Journal of Middle East Studies (IJMES). IJMES uses diacritical marks to represent Arabic letters in the Latin alphabet. For example, the short fatha vowel is a simple “a”, but the long vowel is “ā” with a line over it. A chart of the IJMES letter values is available here: https://www.cambridge.org/core/services/aop-file-manager/file/57d83390f6ea5a022234b400/TransChart.pdf.

Some of the other rules include the definite article “al” attaching to the following word with a hyphen, and attaching to the word with two hyphens, so “فب البيت” would become “fī-l-bayt.”

For example, I have this footnote:

Al-Malik Abdulaziz Al Saud: Umma Fii Rajul [King Abdulaziz: A Nation in a Man]

It should be converted to the following:

Al-Malik ʿAbd al-ʿAzīz ʾĀl Suʿūd: Umma fī Rajul

There's an online tool that converts Arabic consonants and long vowels into IJMES standards automatically (http://alex-hanna.com/ijmes/index.php?q=%D9%85%D8%A4%D8%B3%D8%B3%D8%A9+%D8%A7%D9%84%D9%85%D9%84%D9%83+%D8%AE%D8%A7%D9%84%D8%AF&lang=Arabic&submit=Convert), but the text it produces requires some clean-up, and the insertion of the short vowels.

If you have any experience with this kind of romanization and are interested in this work, let me know and we can discuss it more detail.
