I'm looking for a long term relationship and the above prices are estimates based on what I think the complexity and workload is. It's hard to give an accurate project estimate without seeing the full details. From what's been described, it looks like the kind of gig I'd like to get into. I'm currently working on starting up my remote freelancing gig so this looks like a great opportunity for me. I might be slightly more than what others are bidding on here but I'm good at what I do and can work quickly and efficiently - which will save you the headache and money in the long term.
Experience wise, I've worked with Git as my source control and is well versed in the classic front end stacks of HTML, CSS and JavaScript. I've also got commercial experience in Angular.js, if that's relevant to any of the potential projects in the future. I've worked with APIs and is a WordPress native.
I look forward to hearing from you soon. - Aphinya
