The cost & time is really hard to say,
depends on who you take it too ?,
what their labor rate is ?,
what the cost of the total parts tally of all the needed parts is ?,
what exactly is it that your expectations out of the build ??,
exactly what parts will be used & to what level of fabrication & quality ?
Fab & Specialty shops are notoriously slow, expensive &
can be a handful to deal with, like all artist/talented people are,
get an estimate {as complete as possible, some things are hard to estimate}
& a performance clause {time frame guarantee, that if they are taking too long you'll be charged less}
get both in contract form & get both in writing,
if anything needs to be changed you have to sign off on all the changes in costs...
Google search {many ways it could be phrased}
Hot Rod Shops
Automotive Fabrication Shops
Hot Rod Fabrication Shops
Race Fabrication Shops
Automotive Repair Shops
Automotive Customization shops
Car Builders & Welding/Fab. shops etc.

I'm in Calif. it's a whole different ballgame out here
