monte carlo to convertable conversion

I tried looking it up online, but i couldnt find any info. I want to know if anyone has ever converted their 2000+ monte carlo to a convertable. I was wondering about how much something like this will cost and if anyone knows a good place in the northeast are that does good work. Thanks for your help.

funny I thought of that the other day, turning a Monte into a convertible, let me know what u find out, would be expensive for sure, what's that show where they do yea makeovers on cars, would be a good project..
