19583 Jar resigning and modification

Hello, I have 2 jar files that I need some assistance with. I would like this done as fast as possible, as soon as jar files are returned working payment will be sent. 1) When our applet is run on the site is comes up saying "Digital signature is invalid". We would like some assistance on getting this valid. 2) When the the applet certificate open is lists name, publisher, and from (Just like all other applets). The name says [login to view URL] and we would like it to say something else besides sample. We would like assistance with this also. 3) Lastly, when all changes are done we would like the jar files resigned so when they come up name says our companies name. We have no java experience and I am sure people that do this this is easy. Like I said, we would like this done asap. Please email me at ryan at [login to view URL] if your interested in helping us. Provide a AIM, Yahoo id so I can message you right after receipt of email. Thanks
