Looking for a Registered Serbian Corporate/Immigration Lawyer for Business Invitation & TRP

Hi, I am an entrepreneur currently based in the UAE. I am looking to expand my business operations to Serbia, specifically focusing on the logistics and cargo transport sector. I need a certified and registered Serbian lawyer to help me with the following milestones through Upwork Escrow: 1. Issue a certified Business Invitation Letter (Privredno Pozivno Pismo) verified by the Chamber of Commerce for a Type-C Visa. 2. Guide me through the document requirements from the UAE side. 3. Assist with company registration (APR) and opening a corporate bank account once I land in Belgrade. 4. Apply for a 1-Year Temporary Residence Permit (TRP) based on company ownership. Please apply only if you are a licensed attorney in Serbia with a registered law firm. Please state your total fee for Milestone 1 (Invitation Letter) in your proposal. Thank you!
