Hey mate, I'm super interested in this project. I've read the requirements: you want several drop down boxes containing values queried from MySQL, a calculator for calculating these selected values and a graph of the calculation. I have tonnes of experience in MySQL, PHP and JavaScript. I've also worked with web graphs before, so that won't be a problem as well. I will delivery top-notch results for you, as I believe I'm the best for the job. My past clients loved me and you will too! I'm very communicative, so along with my proficient English, we can skip around the daisy field without an ounce of worry. As a Preferred Freelancer, I have proven to uphold good work ethic and deliver excellent results. I've done several projects related to your requirements and I'm more than enough for the job. Thank you for reading my bid, I hope to hear from you soon!
