Website design is ready, what's next?

Question

HTML

Hello everyone,
We are developing an Internet service,
design, user interaction with the system, all pages in Photoshop layouts are ready,
The service will be quite complex, programming is required, possibly from scratch.
Friends, tell me what's next?
Whom to connect next:
Connect a programmer or layout designer?
Are there specialists who can combine these two functions: program the system and make a working website out of it?
thank you very much for the answers and
I apologize to everyone whose tender feelings are hurt by amateurish questions))

Answer 1

Each department should mind its own business! (с)
One must always participate in the development of a project: a good designer, a good coder, a good programmer. And nothing else. Everyone does their job. Moreover, the project is large and expensive.
If a person does the programming part perfectly, this does not mean that he is obliged to typeset cool. To be able and cool to typeset (cross-browser, cross-platform) is the work of a layout designer.
As well as the layout designer should not write modules to the control system (if one is used).
At the same time, the designer submits the project to the layout designer and the programmer, who can work simultaneously without interfering with each other and, on the contrary, helping each other solve problems.
Only then will your projects be done quickly and efficiently.

Answer 2

Are there specialists who can combine these two functions?

There is, look for it.

Answer 3

Find a smart programmer who will deal with the server side. And ask him, maybe he will do the layout himself, or perhaps there is a "own" layout designer, or at least write down the requirements for the layout.

Answer 4

It is better to hire a performer separately. And for the beginning of the programmer, and after him to call the layout designer.

Answer 5

Don't worry, sell your design on themeforest and that's it =)
