510887 JavaScript to generate image of customers selected options

LOOKING FOR JAVASCRIPT PROGRAMMER ASAP! I carry 3 lines of personalized/monogrammed items of clothing and accessories. For each product, the customer chooses options such as patten, pattern color, monogram initials, monogram color, and font style. On the product page of my website, I would like the customer to see an image of their chosen options (so an image of their selected monogram would appear over the selected pattern with the correct colors). I am looking for someone who can design something that would generate this image using JavaScript. Additionally, the design must work for my website hosted by BigCommerce. -I have website ready pictures -If interested, I can provide you with more details and an example of another website that accomplishes something similar to what I am looking for Thank you!
