If you got jQuery/CSS plugins from marketplaces and need someone install and make them work properly on your website you would consider this service.
With this service, I will:
+ install plugins on your HTML/Wordpress(*) websites.
+ make content demo for the plugin.
This is just installation service not customization.
(*) I need to check your theme/template before.
