Update text in the flyers

I have built 5 to 6 flyer/brochure ( 1 pager) which will depict the pricing plans of my photography business. I have those in JPEG format. I want to change the content in those however I dont have back up files. I have few .svg files but dont know if those are accurate or correct. It is very mini project where we just need to change the text at few places. Hardly should take 10-15 min. My budget is 400 Rs so please bid only if you want to do in same budget
