6 small tasks for Woocommerce/Wordpress Site

Hello, I have a series of small tasks I need completed for my WooCommerce store that uses Wordpress. I don't think they are difficult so please provide me your best price and how long it will take. All information needed for the tasks is contained in this post, please read this whole post before contacting me. Task #1: The product title for my products will randomly be cleared and 'Default Title' will display as the name, instead of what I entered previously. I *DONT* need you to simply re-enter the names, I can do that. I need a permanent fix so that the product titles aren't randomly removed from a product in the future. See attachment "FreelancerJob_ProductTitle" for an example of what I mean. Task #2: When I create an invoice through WooCommerce ("Add Order") it will not allow my customers to pay the invoice and check out. Previously, it would allow customers to pay with this method. When customer clicks on an invoice, it says "Sorry, this order is invalid and cannot be paid for". Here is a link: [login to view URL] Task #3: I have some custom development done on the individual product pages that shows price per unit. The text appears as "Buy 2,500 booklets for $2472.50 at $0.99/booklet" for example. The problem is that this text doesn't appear on the page until a customer changes one the product variables options (size, quantity, etc). So what I need is for the price text to appear as soon as they load the page, not just after they change a variable. Please see 'Freelancer_Price' photo for a visual on this task. Task #4: While customers are browsing my store, the pricing for a product shows up at the bottom of the product entry before they click on it. I have products that don't have pricing entered, so if a price of a product is "$0.00" I'd like for it to show the text 'Get a Quote!'. See 'Freelancer_NoCst' for a visual of this. Task #5: There is a button I use via a plugin 'Request a Quote' that currently says 'Start Your Quote', I want that changed to 'Get a Quote!'. See image "Freelancer_Quote" for visual. Task #6: There is a plugin I use to add photos to a woocommerce order on the product page. Currently the photos that get uploaded are not displayed to the user although they should be. I need the images to be displayed after a user uploads a picture on the product page. Please see image 'Freelance_AddFile'
