Build an Online Store using Wordpress -- 2

I have the design that i need with CSS stylesheets and HTML for home page/ inner pages. Its an existing website using cstom PHP code. But I have realized that its not very flexible using custom PHP. hence I have decided to go ahead with using Wordpress for the website using various plugins etc that it provides. I need : Re-configure website using Wordpress. Use various plugins it provides for: - E-commerce capabilities - Custom User login/ register form (preferably with facebook login) - Social media configuration (like facebook/ twitter G+ etc.) - Secure Site (using HTTPS only for secure pages - I have SSL certificate with hosting company Go Daddy) - SEO capability - Newsletter capability (design of a template and schedule newsletters etc may be using a plugin) - Search facility (may be using google search). Ajax search like amazon search - Facebook/ Google + / Twitter landing pages - Design enhancements for home page as well as look and feel of various internal pages - Various forms like contact us, feedback etc and their configuration etc. - Invoicing - Products image editing etc for the products to be put up on the website initially (around 50 projects) I will provide the content, SEO content, products myself. Hence this is a very small project. Kindly provide genuine and honest quotes because I am aware of Wordpress and the power of its plugins. Thanks.
