Creation of "clients database" and for each client "activities" must be stored. Multiuser, with login.
Need good design (you'll have layout to follow), use css in a separate file so style can be changed easily.
If interested I'll give you more details in PM.
Ready to start. We're a team of experienced freelancers with vast knowledge in web-design and web-development. Estimated time to complete the client management small aplication with multiuser is up to 7 days, maybe less.
