SEO Titles & Meta Descriptions - 100 x new Shopify web pages

Hello,

I am launching a new E-commerce site built in the Shopify platform this month and need help writing SEO titles and meta descriptions for each brand/product page.

Meta Title - 50-60 characters maximum length.
Meta Description - 150 characters maximum length.

Each brand/product variant must be unique.

Please provide your costs based on a set number for all 100 to be done as 1 x complete batch with all information to be included on a new CSV file for uploading to Shopify.

Work would need to be completed by mid May.

Any questions or queries, please let me know.

Regards.
Simon.
