Improvements

Please have a look at www.ascendlearn.org and submit your proposals for further improvements. The original web builder did a great job but I am now looking to get it even better aesthetically and functionally. I welcome any proposals that will make the website stand out from the rest, not just by how it looks but also how it functions. I want it to be simple, responsive, clean and professional. The website was built in OSCLASS but I don't mind migrating it to Wordpress. The full company name is Ascend Learning Partnerships Ltd but I am branding it as ALPS.
I have had some offers but the majority of them didnot disclose what improvements they will make so please make this clear. Thank you.
