My company is interested in hiring someone to setup umbraco on our server as well as integrate the aforementioned signup forms with umbraco. The signup forms are currently built in regular asp.net using LINQ to insert the information into the database. If someone is familiar enough with Umbraco to handle this and make the signup forms work with the Umbraco membership class then i can show you the current forms, database and such in private so we can work on a price. You can contact me initially at mikehomecom@yahoo.com and i can give you a more reliable email from there (trying to avoid spam).
