Startup Idea : Connect buyers and sellers of sponsorship

Businesses are constantly flooded with sponsorship proposals from brands/events which aren't aligned with their company vision, and they hardly waste time reading these lengthy proposals. Let's build a web-based platform for all sponsorship needs. Users seeking sponsorship can list their proposal online(only the most important information is required) and sponsors can easily find the ones which suit them. Sponsors can contact and speak directly to listers via the platform. Finally, sponsors can purchase sponsorship packages online, with a nominated portion going to charities. List. Browse. Connect. Purchase similar to: http://www.sponsorist.com/ http://thesponsorshipcompany.in/ While I understand multiple coding languages, I'm not a professional - in need of web development support. Sketched a very basic wireframe which I'm happy to send to those interested. Based in Australia where there is a growing trend in sponsorships.
