IT Distribution Ecommerce on SHOPIFY

I am starting a new online business from scratch as I have access to IT hardware and access to technology products for sale. I have started a shop using default template of shopify. After conducting my research I feel shopify is the ideal platform for me. Desired launch date is Mid April (2 weeks). I need a shopify expert to: 1. Add large bulk of products and be able to take raw product / items details from suppliers data feed files and convert them to suitable import product files for spotify. 2. Configure an appropriate these to work best as a IT /technology distribution website which has over 1000 products. 3. Have filters suitable for the page e.g. on a the refurbished laptop section filters on the left to look at: Intel i7 Process laptops, 8GB Ram laptops, 14” or 15” laptops etc. Shopify has pretty easy to use integration with Payment gateways etc. we will be running with Stripe and Paypal payment options. 4. Freelancer must use their own initiative to find suitable images and product description formatting to fill in any "common sense" blanks when creating this website. e.g. you have a list of Apple iPads to add to the list in option of White and black, you will source the image of the product yourself if missing in the data you will be provided. 5. most suppliers provide csv or datafeeds. we need to be able to manipulate these stock, inventory and pricing data feeds into shopify system. suggestions and ideas on ideal platform for the needs above are welcomed. This website needs to come forward as a large distribution website with large product lines and a corporate look and feel. Such as lambatek, ebuyer, [login to view URL] etc. I already have website started on shopify the winning freelancer will be given access to my shopify account and will need to work directly on the current site / account.
