Website for my promotional advertising company

Website overhaul. Rebuilt from ground up with mobile and tablet screen support. Most of the content already exists through external links but would like a consistent feel for pages that house these links with use of iframes or similar. I need some time and ideas for page layout so that I can choose the best design for my needs. Originally I was leaning towards bootstrap or similar but I think that maybe I should have the site built with more flexibility in mind for future growth. This is a simple project with limited pages needed but quality user experience is required. My company is a printing, embroidery, uniform, safety awards, promotional items, etc. We distribute products of many manufacturers with clients custom logos. We also produce and decorate a multitude of products in house. We have multiple custom promotional item and apparel web catalogs that our clients search and use constantly so I would like to integrate those into the web design or possibly use CSS to extract the info from that catalog to our own product pages. A similar company would be [login to view URL], [login to view URL], etc.
