Hi, we have read all the requirements and we are very confident to do this project from start till end. We definitely have some questions when we discuss project with you. Due to the change of bid system at freelancer.com, they ask freelancer to submit the project proposal at the time of bid. But it is not the right way, initially we can go through the requirements but we definitely need to spend time to write the proposal. Also they provide no place or private message unless you contact us, therefore we cannot submit the portfolio, examples site and our creative work. Also we do not post the portfolio and work examples publically to avoid other people copying it and claiming as their own. Please check our profile and the reviews given by the clients who have worked with us and see how much they appreciate our work by giving us their wonderful word in shape of feedback. Please send us a message so we can submit the links of our portfolio and then you can review and if you like we can start discussing project to help you to reach the final decision. We shall finish this project in timely manner and will finish it in time. We offer IT, Web design, web development and Smart phone application development. We also give life time guarantee to our work. Thanks
