479167 Template modification

I am looking to purchase this template here to base the site on: [login to view URL] Here is what I would like to add to the template: -About Us -Contact -Sign up (requires monthly membership fee, so Paypal integration) -How it works -Login -Apply (for service providers, they don`t pay a fee, they are required to complete several fields in the application process) One logged in as a member: -My account, edit info, cancel membership -Browse and search service providers -View service provider info (such as about, contact, link, google map of location) -Download coupon, promo code Once logged in as a service provider: -My account (edit info) Wordpress Admin: -Add, delete, edit, members and service providers, -Stats I`m looking for the cheapest alternative since the script is only $10. How much to incorporate those feature and changes to the script and when could you have it done. Thanks, Ben
