Mark,

As far as I know there are no companies currently offering a budget kilt sportcoat.

It sounds like what you need is a tweed kilt jacket. Your best bet is to find is to search XMTS and read all the Jacket Conversion threads. Here is one my lovely Flame-Haired Celtic Amazon Goddess did that is pretty detailed with photographs:

David Dalgish and his wife have also done many excellent jacket conversions. This is a great time of the year to find sportcoats on clearance or perhaps you will get lucky and find a real bargin at a second hand store.

If you don't feel you have the skill to do the alterations yourself a taylor or seemstress should be able to do the work for around $100 (depending on what features you want in your jacket.)

Good luck

Jamie
