Recommendations to build my Shopify site?

There is always someone on here that seems to have a good answer to life's problems so I thought I'd ask!

I'm starting a small online business venture, already up and running but need to build a Shopify website. The site is designed, has a site map and wireframes. What I need is a small agency who can take the design sample pages and build it out. I guess in an ideal world an agency as if I ever need support they can be reached, but maybe it is just someone who builds these sites.

Anyone know anyone. Site is ready to be handed over and I'd like it finished next month.

Thanks both. Some good points there and the payment thing is something I am looking at.

Really do want someone to build this site as there is no way I'm doing it. Ideally a company that has done a few should we need some support.
