I have experience developing web based CMS portals for companies with multiple clients. My bid is to develop a portal system with two levels of access; user and admin. Admin users will have access to access/upload/modify files for any user, and users will be able to access/upload only files tied to their account. I will also assist in setting up SSL for connectivity, either on a server you own, a VPS you rent, or on a shared hosting account. My bid does not include acquisition of said hosting hardware, but I can direct you to one or more reliable providers (just don't go to godaddy, please). I will expect the milestone to be created before work can begin, and will request its release only after the project is deployed. I look forward to any questions you have for me, and hope to begin working with you soon, thanks!
