Hi Angrychickenm,
If I understand correctly you have a design but haven't bought a theme yet?
Depending on the design I'd probably be faster and the site would end more lightweight, if I start from scratch. But I'd have to see the design first.
I use Bootstrap for making a site responsive and have my own starter theme (just the basics) in WordPress I use. You can see it in action here: [login to view URL]
The amount I quoted is just a placeholder, upon review of the design I can give you a fixed price and timeframe within which I can build this.
Installing WordPress on your server is no problem once I have FTP access.
Thanks for your consideration!
Regards,
Tim
