Integrate maps API with Freelancers. We have properly licensed Freelancers script which you will modify to take address in addition to the normal details. Addresses will be taken from both the freelancer and buyer. Must be able to search for jobs/freelancers using map and keywords. Final deliverable is one-click installation code (via HTML) which modifies a fresh Freelancers install.
Working hosting environment provided (MySQL/Perl/PHP/etc.). Please discuss further in PMB and agree on spec.
