Seamless Pattern Designer: Authentic Bosančica (Medieval Bosnian Cyrillic) Monogram for Apparel

We're a Bosnian-heritage apparel brand (LJILJAN) creating a premium jersey/apparel line for the diaspora community. We need a seamless, repeating monogram-style pattern built from AUTHENTIC Bosančica letterforms — the medieval Bosnian Cyrillic script used from the 12th–19th centuries (seen in the Charter of Ban Kulin, Bosnian stećak tombstone inscriptions, and Franciscan manuscripts). This is NOT a request for modern Cyrillic, a generic "Slavic-looking" font, or invented symbols. We need the real historic letterforms, traced or adapted from primary sources or an existing dedicated Bosančica typeface (e.g. BosNow, Kulin Ban, or Stećak fonts). WHAT WE NEED A tonal, seamless, repeating pattern (similar to a Burberry/Louis Vuitton-style monogram print) built from actual Bosančica letters — not modern Cyrillic substituted in. Letters should be clearly drawn from real Bosančica sources: the Charter of Ban Kulin (1189), stećak tombstone inscriptions, or a verified digitized Bosančica font. Final deliverable as vector files (AI and/or EPS), CMYK + Pantone color-matched, sized for sublimation printing on apparel. Pattern must tile perfectly with no visible seams at scale. We'll provide brand colors (navy/blue or bone/black/gold options). TIMELINE & BUDGET Turnaround: 1 to 2 weeks from project start to final files. Budget: $150 fixed-price, depending on experience and revisions included. Open to discussing scope if you need more time to do the sourcing right. NICE TO HAVE Familiarity with Bosnian/South Slavic heritage, history, or diaspora design work. Experience with historic/calligraphic script digitization or paleography-adjacent design. Portfolio examples of monogram or heritage-pattern work (fashion textile patterns, luxury brand monograms, etc.). HOW TO APPLY Please include: Examples of past pattern/monogram or script-based design work. A short note on how you'd approach sourcing accurate Bosančica letterforms (do you have access to a digitized Bosančica font, or would you trace from manuscript sources?). Confirmation you can deliver within 1 to 2 weeks, or your realistic timeline if longer.
