WTH php coder - custom phpbb coding work

I need someone to help me edit an SEO plugin creating seo friendly urls, rewrite a sitemap plugin to make it work and add meta descriptions to each thread .

friendly urls work

sitemaps I have a base code (short) that you can rewrite based on the friendly urls and meta descriptions need to be coded from scratch.

i will only pay for working code, no problem to see it on your server first.

work for maybe 5-6 hours tops, $200 reward (I can pay more if not adequate).

I will send my code on request.

I can do it, if you are ready to increase the price
I have good command in Plugin Customization & Creation
