Greetings,
I have read Project Description & checked the links of quiz to understand the type of quiz you want in your website. Actually we have not done exact similar website in past, as every client requirements are custom but we developed a survey type Application for Hotels & few others. However, let me assure you one thing that working with our developers, you won't have any technical hurdles, as we have worked on variety of projects in past. In fact, I will assign you 2-3 dedicated senior PHP developers and a team lead having 8 years of experience.
Please drop me a message thru' PMB to start further discussion about your project, as we cannot write much on this initial message bard due to limitation of characters.
Our current bid is just a ballpark estimate but once you respond us, we can then negotiate it & finalize, as we are flexible in prices.
Please check out our Freelancer profile https://www.freelancer.com/u/leadconcept.html, as we have delivered many successfully projects lately and let me know, if you want to see some of our recently developed projects.
