Upload 140 items in my Magento Ecommerce Store

I have a MAGENTO built website for which I require about 140 products to be uploaded through the backend of Magento. Data entry work to be done on them such as Title, Description , pricing and adding some other details etc. which must be compatible and suitable for SEO. Winner bidder has to be very confident in the Magento Back end and being able to upload products with Magento. All 140 or so products entered will be divided by categories. There will be no training provided the winning bidder has to know what to do regarding the use of the Magento Back End. Product Images will be provided. Also I will send you all information need it - category, subcategory, title, price, description. You just have to enter it in my store so it is quite simple. I demand for a near perfect result from this and I won't release payment if the job completed is not up to my expectation. I had previous experience of freelancers who just message me telling that they can do a good job , Which was NOT the case. BEFORE YOU BID PLEASE READ THE FOLLOWING!!!! I need this done in 48-72 hours maximum! If you can not start immediately and you can not finish this project on time, do not bid on this project. By bidding and accepting this project you agree on the condition that....for every day that you are late you will loose 30% of the commission we agreed upon. Also...bid only if you are experienced. If you can not do this job and you make me explain all over again and again - you will not get paid and I will leave a negative feedback!!! So only bid if you have been uploading products in Magento Community store before and you are very familiar with the job!
