I'm working almost 2 years as a freelance and my main client is a London company.
I'm doing jobs for the front-end mainly and we always use angular Js. In this time, I gathered a good structure for the project and I control technology so the work required won't be a challenge for me.
Anyway, we'll be in touch in order to specify better the job to be done and then I'll be able to give you a due date. Apart from use angular and jQuery, this last will be used just for a few specific things or maybe for nothing because angular provide you with a lot of jQuery characteristics but oriented to be used with angular so they're better, we could use also bootstrap, it's an angular based library which contains some components like dropdowns, date pickers, etc.
We are in contact.
