Laravel Website Function Addition and Fixes

I need a skilled Laravel developer to add a specific function to my website, as well as fix a few issues.

- Enable “lazy” page loading
- Add cart function
- Fix Error 500 After placing an order
- Change the font
- Add sale function
- Make the text menu bigger and add icons next to it
- Compress images on upload
- Hide some fields on checkout

I will provide google docs with complete details and screenshots for easier understanding.
Small budget. Need this to be done ASAP. If you can't do this, please do not bid. Thanks!
