Evaluation of technical solution for new web shop (products = downloads)

I want to set up an online store for downloads (Excel files with solutions for typical business tasks). Next to the shop itself the site shall provide a blog with 'tipps and tricks', and a newsletter. Everything shall be to the largest extent possible based on existing"out of the box" webbased technology, so I can do with a minimum of customization and individual coding. To decide with which software / provider to go, I need a research / evaluation of exixting 'state-of-the-art' solutions for the various functionalities. The final decison will have to include - webshop solution itself - payment solution - blogging funcionality - newsletter - hosting provider (- if you suggest to take anything else in account, please add to the list) The most critical factors from my point of view are - SEO friendlyness / optimization - usability, 'user experience', check-out process - performance (speed) - technical integration (shop / newsletter / affiliate programs) - marketing integration (campaigns, special offers, landing pages, coupons, etc.) - security - scalability (volume/traffic, additional languages, additional products or services / product categories) - availability of resources for individual development / customization and support (e.g. support by provider, freelancers available in the market, etc.) The final solution may be either an integrated suite, or a combination of best-in-class tools for each functionality (e.g. Blog by WP, webshop by provider X, newsletter by provider Y, etc.). The latter would of course stress the integration issue. Desired outcome of this job: - A (structured) report, giving - an overview of the solutions that might fit the above listed needs, - including pros and cons for each of them, and - a recommendation / priority list from your point of view as an expert. Regarding your offer: If you know the market and are familiar with the solutions available, please suggest **cost and timeframe** for this project. When offering, please provide some information about your background, indicating your qualifications for the job. Thank you, I am looking forward to your offer!
