Build a simple, responsive website to look good on mobile devices

Hi everyone! We need a professional web development team to develop a simple, responsive website for us, which looks good on mobile devices. This is the simplest, leanest product that we plan to launch. We are really trying to keep costs to a minimum for this 1st stage of the product please. We would love to develop a long-term relationship with you, so if you do a great job, after we release it, and get feedback, we will have lots more work for you developing future functionalities for this site/app. Essentially, this 1st version allows users to: - Create a Profile - Create a Crowdfunding Project, and share it with their linked social networks - Donate to others' crowdfunding projects - Track your giving. Please note: I am not a tech or an engineer - if you notice any simpler way to do this, feel free to suggest changes to my screenflow. We would like to launch as quickly as possible (ideally: within a couple of weeks). What language do you think will be most efficient to develop this site? You'll notice my screenflow is based on how the site will look on an iPhone. I don't really mind how it looks on a computer - if we can focus on making it look similar to my design on smartphones, I think that's smartest (because moving forward, most users will be using our site via their phones, but in the short-term, some users will still prefer to use the website to type their data, attach images to their profile, upload relevant .pdf when creating crowdfunding project etc...). Don't worry so much about style/design for now - we are happy to create this as a very basic framework, and just focus on fast, robust, secure, simple functionality for now. You'll notice I've added our logo as a watermark on all pages - for now, this is enough for branding I think. Maybe you can also include our basic colours, black, blue, and grey (I've attached our logo so you know our colors). Basically, a simple style like iOS7 is the look we are going for (but again, if it takes a lot of extra work, we can do this in a later version). After v1 has been launched, and we get feedback, we can think more about design/branding then... I hope this all makes sense - I guess the main points to remember with this project are: - Keep it Simple. Focus on usability (UX), not design. - Keep it Cheap. This is just our 1st version. We'll be happy to invest more for future versions, AFTER you can show us the simplest, working v1. - Be creative. If you think any of my ideas are too complicated, suggest a simpler alternative - I'd love to hear your opinion!
