Retro Bison Sticker Design 4 x 4

Hello, my name is Ian Mills. I am the marketing director for a cannabis company in Oklahoma, USA. I am looking for someone to convert the sample design attached to this proposal into a sticker that we can hand out during promotional events. The sample design is of a 70's era alpaca. I would like the alpaca replaced with a bison (I will attach an example of a bison as well). I would also like the sunglasses updated to something more unique/eye catching. Essentially I want the exact same background but with a bison wearing "cooler" sunglasses. (I will attached an example of the sun glasses as well). I have a small budget for this sticker of $60 USD. Thank you for your consideration, I look forward to your bids.
