Hey there Bankman,
You asked for those of us who have done work similar in the past, well we worked with Skurups Sparbank, a savings sub-devision of Sweden's No.1 Bank. We also have expertise in creating mobile Apps.
I myself am a programmer and work as a freelancer on the side. Our team however has 3 programmers as well as Timothy Wilkinson, our graphic designer, who is responsible for amazing pieces of work with well known brands and companies such as Disney, SVT (Sweden's biggest television channel), Logitech and much more. He is working with me and is one of very few who could offer you exactly the design, image and real IDENTITY you want and yet deliver much more.
We are available by email, phone and Skype any time you need us and I mean that.
We will set up the secure network and get everything done for you step by step. We can look at the specifications, designs, drafts and so on over coffee, on Skype of course :)
We offer long term support and adjustments with this project and will assign hours of maintenance work after everything is finished in order to make sure things runs smoothly.
I believe we can give you the service you're after. Timothy and I are looking forward to meeting you.
Sincerely, Giles
