Greetings,
I have read Project Description & understood the overall requirements from the attached document, I have also seen your existing website, which definitely need complete re-designing using WordPress CMS but your budget of US $500 is very low, so please let me know, if you can be flexible.
Please drop me a message thru' PMB to start further discussion about your project, as we cannot write much on this initial message bard due to limitation of characters.
Please check out our Freelancer profile https://www.freelancer.com/u/leadconcept.html, as we have delivered many successfully projects lately and let me know, if you want to see some of our recently developed projects.
Look forward to hearing from you.
Regards,
YK
