Hello,
I can make this responsive theme for you, most of my WP websites are responsive. The deadline is 7 days right?
My name is Fabrice Pallaud, I'm a WordPress web developer & designer. My brand name is Baia Design (you can easily find me on Google, first result).
I just registered on Freelancer but I have 5 years of freelance web design experience. Please take a quick look at my portfolio here on Freelancer or on my website.
My goal here is to build a reputation and positive ratings, so you can be 100% sure I'll do everything necessary to secure your satisfaction with this job.
Best regards,
F. Pallaud
