Hi. I have a good understanding of what you require as I manage and maintain an ecommerce store built on magento daily (not just the catalog but I also take care of orders, banners and all IT requirements).
I've done bulk uploads many times and will require a copy of your CSV and access to your admin panel to export the profile to be used for importing the products. I'll then make the necessary corrections, and explain to you what was causing the issue.
I've been in the IT industry for 10+ years and hold two Microsoft Professional Certificates (Systems Engineer and Admin). There's no language barrier for us as I'm from the Caribbean. By hiring me you know you're getting a professional who is highly committed to achieving goals. Please check my profile/feedback as well, as you will notice all my clients have been satisfied 100% by my expertise, accuracy, efficiency, and great attention to detail.
I'm looking forward to working on your project as the start of a healthy long-term working relationship, and will complete this as per your desired time frame. I'm also open to communication via skype or email if you find it necessary. Kind Regards, Kenny.
