Secure FTP Client Request for $$ cost

At this stage I require an 'estimate' for the following. An SSL capable ftp client that will connect to a regular unix based ftp server daemon running under STunnel. (SSLFTPD) This Client Application will require two versions a Windows Version and a Macintosh Version. The final client software will also be expected to reflect my clients company logo/design styling. Thanks. ## Deliverables Gathering estimates for information purposes to pass back to client.. for project costing. ## Deadline information Just info gathering for cost purposes. We are weighing up the pro's & con's of a web based file upload against a dedicated desktop application. The Client has now decided to go with a web based solution.
