I want to rebuild my old wordpress site to new modern stack The Current Status: Source: WordPress Multisite (WPBakery Builder). Content: Approx 60 items in a "Portfolio" Custom Post Type. Structure: These items have a Parent > Child hierarchy (e.g., Candied Fruits > Amarena). The Job (Turnkey - You do 100% of the work): Setup: Install fresh WordPress + GeneratePress (Free) + Polylang. Manual Cleanup & Migration: Move all 60 Portfolio items to the new site. CRITICAL: You must strip out all old WPBakery shortcodes (e.g., [vc_column]). The new content must be clean text/images in Native Gutenberg Blocks. CRITICAL: You must preserve the Parent > Child relationship so the site structure remains identical. Design: Create ONE "Single Post Template" (using GeneratePress Elements or Blocks) so all 60 product pages look consistent and professional automatically. SEO: Migrate Meta Titles/Descriptions (Yoast data) to RankMath or Yoast on the new site. Requirements: URL Preservation: Old URLs must work exactly as they do now. (Check if /portfolio-item/ slug is needed). Speed: Score 90+ on Mobile Core Web Vitals. No Elementor. Use Gutenberg/Greenshift/Kadence Blocks only. Budget: Fixed 5,000 INR. (This is a clean-up and migration job for approx 60 items).
