Volunteer and Sponsor project

Ok we are working for a none profit organization and we need two simple scripts that can be easy to use. Project 1: Volunteer This one will have a log in section were volunteers will upload only their avatar and add a few basic information when saved it should appear in volunteer page. We want to keep it as simple as possible nothing fancy or complex. We have a sample demo to show you how it should work so contact me to know more information. Project 2: Sponsor script This one will allow visitors to buy an ad space somewhere in the website. They can pick the ad space they like pay using paypal when they pay they can upload their logo and add a small description. After a month or a year depending on what the admin sets it to if the visitor does not renew it automatically gets removed from the site but remains in their account if they do decided to renew it in the future. More than one buyer can buy a ad section if they do the banner can rotate but this will be determine by admin. We can provide a demo to show you how we want it to work. If you can do this please contact me and ill provide more information. Please only serious freelancers and who know what they are doing. Contact me to know more information thank you.
