Ottoman Archive Genealogy Research & Translation

I am looking for an experienced researcher who can conduct genealogical research in the Ottoman Archives in Istanbul concerning a Bulgarian Christian family from the Plovdiv (Ottoman Filibe) region during the 19th century.

At this stage, my first objective is to establish what relevant records survive and whether they can be used to reconstruct family relationships. More specific family names, locations and dates will be provided privately to suitable candidates.

I am particularly interested in researchers with practical experience in:

-Ottoman nüfus defterleri (population/census registers)
-19th-century Ottoman genealogical research
-Christian/non-Muslim populations of Ottoman Bulgaria or the Balkans
-Ottoman tax, property and other administrative registers
-Ottoman-Turkish paleography
-Research in the Ottoman Archives in Istanbul

The eventual objective is to find primary historical records that may identify individuals and family relationships, including population, birth/marriage-related, property, tax or other relevant records.

For records discovered, I would expect clear archival references/call numbers, and where possible high-resolution scans or photographs of the relevant documents. Relevant entries should be accurately translated into English, particularly names, dates, relationships, places and other genealogically important information.

When applying, please briefly explain:

Your experience researching Ottoman population registers and other archival material.
Whether you have previously researched Bulgarian/Balkan Christian families in Ottoman records.
Whether you have direct access to the Ottoman Archives in Istanbul and can conduct research there if necessary.
Whether you can first identify the relevant surviving registers and archival references before beginning a larger research project.
Examples of similar Ottoman archival or genealogical research you have previously undertaken.

Please do not send a generic genealogy or translation proposal. I am specifically looking for someone with practical experience locating, reading and interpreting original Ottoman archival records.

The project can begin with a small initial research phase to establish what records are available and assess the potential for further genealogical research.
