Please help me evaluate my skills

Hi,

I’ve been coding HTML&CSS for a while and I want to learn and practice more but I need your help on this.

I recently coded this page http://www.weddingcertified.com/certified-wedding-vendor/
and I was wondering how many working hours do you guys need to complete a task like this. Only HTML&CSS, responsive.

I know the coding on this page is not perfect, but I need to figure out if I work fast enough.

So, how much time you would need to code this page if you had the design?

Thanks a lot!
