Font designers / finders

Hi there, I would like a full alphabet font either matched or designed. I have attached a font i like called GROWLY GRIN, but i don't like the jagged edge, but i do like the shape of the font. I like the thickness and narrowness. It's only the jagged edge i don't like. I've made a small example myself which I've also attached, but i don't know how to turn an illustration into the digital files i need. For e.g. EPS, JPEG etc. http://www.fontspace.com/cumberland-fontworks/growly-grin/18476/charmap Please could you ket me know teh turn around time and also a rough quote. Many thanks, James
