I just read your short description about your web project. As per my experience with out taking a big analyze about what you actually did & what left in coding mainly functionality development part and in which language it is built. So before to start I want more information regarding the project.
I offer you a minimum cost & timeline that will not let you down & it is also noted that after fare communication I will tell exact cost because it can be less & timeline. In the communication when I will get all the information from you I will provide overall process to develop the project.
My work procedure is like watch TV before to sleep, mean, each day You will get update from me, from there you can find out end of the day what I did actually and also end to end communication from my end.
About my work, I don't tell in words, it tells my work. I do maximum e-commerce site. If you want I can provide my portfolio.
Why I? I started my career as a web developer for 5 years & working as a freelancer from last few years, now I have well dedicated team to work any kind of web-based project with PHP, Codegniter, Wordpress, Cake PHP, Drupal, Magento.
Thank You.
