Please recommend a geneologist for 1800s Breslau

Dear Niederschlesien list,

Could anyone recommend someone that I might pay to do geneology research for my ancestors from Breslau, Germany?

I think the next thing I need are church or birth records, probably from what is now Poland. Specifically, for Johanna GROSHNANN or GROSSMAN (b. 3.5.1824 (Ransern) d. 2.2.1893) who married Thomas LICHTBLAU (b. 7.1.1820 d. 13.4.1885).

Does anyone know how much it might cost?

Thanks,
