Resolve issues in Wordpress based website

I have got a website recently developed, which has some small but important issues not resolved yet. I would like to hire a freelancer who is great in wordpress and has sufficient introduction to woo commerce. These are the following issues, which needs to be resolved. may be a maximum couple of hours of work for good expert. 1) Mails are not sent to customers nor is the contact form sent to admin. There is some error thrown by phpmailer() php file, which needs to be resolved. At the end of resolution, the user should get all the mails and I should get the contact form data as mail. Mail server is Gmail and Host server is Godaddy. I do not want my mail server changed, should be gmail. Talked to godady. They say, SMTP relays have to be updated. 2)In woo commerce, as soon as an order is placed, I would want a mySQL database be created which has user data and order details. (Right now, woocommerce does not have proper summary DB for that, and plugins provide indufficient info) 3) Woocommerce has instamojo payment gateway integrated. However, for failure or cancelled orders, it lands on failure status page and does not redirect back to dashboard. Need to update the redirection in code to that page 4) There are two payment options. Payment by Cash or Payment through gateway. I would want different thankyou pages for both cases, showing different set of information. The content and html css coding, I can do myself. In a way, we already have one thankyou page from woocommerce, all we need is redirection to another one for payment by cash. 5) Last, XML sitemap plugin has been activated. Need to update the xml document, right now, it just pings with only home page. Would want to ping with few more links to google.
