94 green drop top

i need some recommendations for upholstery/interior shops in the northern va/dc/baltimore area. I need part of my drivers seat reupholstered and a new side bolster put in, and have only been able to find one shop so far, and they quoted me $250. Id like to get some other opinions, cause that sounds a little steep to me for what actually needs to be repaired. do you think i could find a replacement instead for cheaper?

im located in college park, MD

thanks
