Update the design of the site

The design for the project needs to be updated.

I see 3 paths.
1. Draw from scratch. Then make it.
2. Buy a template, pull, comb the design.
3. Use someone's purchased template. Change the design.

Whatever the case, an important criterion is the cost of work.

Functional (partially implemented by plugins):
- the conclusion of articles on the main
- viewer with a lead-up
- popular articles on views in different categories (games / applications) for the period
- comments
- "Naturished" menu to the top screen


WordPress has a few plugins, but not critical ones. The main purpose of the change in design is uniqueness and professionalism.
Please offer solutions to my problem.
Authors are also invited to the project.
