I accept bribes. j/j
The best way to go about it for this case is to find an Ambassador class ship model that has already been made for SFC, get permission from the original author to use it, and than keep bumping your request on the forum. If you are not picky about quality or specific details, that is enough. If you are a little bit more picky, you need to describe exactly what you want so that they guy doing the work for you doesn't have to go back and make changes too often. The key is to get someone else to see your vision and get them excited enough about it to last the whole project. More interest = more time spent = better model/textures.
So, Alphageek, throw some details up on this thread, give us a link to a model you would like to use, and I am sure one of us would be happy to work with you on this.
