I am very sorry to hear your troubles. But, I have to agree with Don. You just need a little confidence that you can do it. It's really not hard to patch the seems. Give Myself (Ron Buckle) or Will Sherrer a call tomorrow during the day at (705)719-9111. We would be glad to give you advice to help you through this. We can't come do it for you, but, we can try to help anyway at all.
Oh and don't worry to much about mildew. Saltwater isn't condusive to mildew growth. Just get as much out as you can with a wet/dry vac and get fans on it to dry it out.
