Hi nice to meet you. I am Troy.
I have analyzed your requirement and your site. It seems you want to improve your business as an advertising agency.
Now about the looks, you had created a simple HOME page just with the HTML links of advertised websites. The thing is that, if you want your agency to improve the home page should be a Landing page, which would show your Expertise and Nature of your business.
Next, your landing page would tune up directly to your website where the categories would show up with sunning appeal. I will show you some websites and the designs will be done on your recommendation.
Logo,newsletter, member's login , e-mail marketing (mailchimp) etc will be done. Other features like SEO will charge extra cost.
Thank you for your time,
Regards
Troy.
