Migrate 60 "Portfolio" Items from Multisite to Single WP (Clean WPBakery to Gutenberg)

Job ID: 40091396

Budget: ₹600 – ₹5,000 INR

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).
