Hi, I'm very interested helping you creating your PHP/MySQL application to upload your spreadsheet data. I can do this job quickly with high quality, because I've already done many projects like this. I’m a software engineer with more than 6 years experience in PHP and MySQL technologies.
Please send me all other details if you have about your project, so we can start ASAP. I'm available, and can start immediately. Looking forward to working with you. Thank you for your consideration. Regards
