Build a Website

i need some help setting up a business website im trying to launch. Its based on sales and hosted by by a dance team and i have a theme already installed but i need help tweaking certain things. I need the following: - Helping quicken load times (its very slow) - Add a subscribe now popup/bar - Add space for future ads - change banner/logo - add a slider that can be integrated into certain posts (not on homepage) - Spam plug in for comments - Instagram widget - Social media sharing buttons on posts/pictures (pin it, tweet it, etc) - possibly adding a polling widget - adding linked within posts Please get in touch if you think you can work with the above in a fast turnover time. If I had a little bit more knowledge i think i couldve done it myself but seeing as my experience is all in journalism i would rather rely on a professional and make it the best it can possibly be.
