Changing Text Font in Sketch

I'm modeling some letters to etch on some 16 guage SS and am trying to match some font giving to me from a customer. It's old english and the font in SW is slightly different. When the lettering in the model it is basically a sketch? I want to know how to adjust the lettering to match my customers. I can't move the lines like in a typical sketch. Please help if you can. Thank you
