Hello,
I would like to create your website using Wordpress as the backend. I have years of hands on experience with it, and I am skilled in html/css/jquery/php and wordpress custom functions. Creating your website will be no problem for me, and we can use woocommerce as the store backend.
I think it's best to purchase a pretty theme for it, as it has included responsivity. You can show me some websites you like so I can find a theme for you to pick from, or you could find it yourself, and then we can edit it if neccecary.
SEO is a very important aspect. I will install a SEO plugin which helps to fill in metainformation, keywords and edit how the site will look in search engines like google and yahoo, etc. It will also create a sitemap that is important for rankings.
As for security, this is a low risk website, but it will anyway include a lot of wordpress security tweaks like removing the ID 1 user, blocking brute force attacks and blocking spam login attempts, etc. As for the timeframe, the website can be finished in FIVE working days, starting from tomorrow.
Please let me know, or feel free to ask something if you have some questions. During the project development, we can constantly communicate through skype or email.
Kind regards, Luka
