We are a 15+ years-old Software and Web Development organization, based in Largo, Maryland, USA with 130+ in-house experienced developers and creative designers. We got the understanding that your website which is built using custom PHP, needs to be enhanced in the aspects of designing.
It would be better if you could share your website's URL with us so that we could propose our offer accordingly.
Could you let us know your entire project requirements?
We would use HTML5, CSS3 etc to enhance the look and fill of the site. Our creative designers would craft exquisite and visually appealing yet clean and professional banners, photos or whatever you require for your website.
So we are looking forward to discuss with you further on the entire project requirements.
