We are a team of designers and developers with expertise and experience in Photoshop, HTML5, CSS3, PHP, AJAX, JQuery, Angular JS, XML, Wordpress, Joomla, Shopify, Bootstrap, CodeIgniter, Laravel, Google Map API and MySql.
We have designed and coded many custom sites and applications of varied extents and complexity, including many e-commerce sites. We have coded and integrated custom CMS in core PHP for many sites enabling easy management of products etc from a password protected admin section. We have also integrated Wordpress and Woocommerce for many others.
I have read your requirement overview and have studied the PDF. Woocommerce will be fine. I would suggest you give us the opportunity to build the complete site (including the static pages).
I need to clarify some finer points - you have mentioned customer login but no registration/ sign up?
On checkout why are you asking for Employer address?
I will need to know which of the lens upgrade options can be selected simultaneously and which are options (checkboxes or radio buttons). For the frames - there will be no categorization/ search etc.? It will help if you can share the theme that you propose to buy / install and any reference sites that offer the same functionality.
Complete details will enable me to assess scope of work precisely. I will revise / confirm my bid accordingly. Detailed specifications and inputs will also help me to make an informed commitment and deliver as required.
