PHP Modification: 1 month -> 1 day

I spent a whopping $29 for a turnkey legal search website. It seems to be exactly what I want with one minor exception: It allows me to easily select whether a person can advertise on my site from 1 - 12 months. However, I want to change the 1 month period instead to 1 day. Basically, I want to give the person the option to post their ad on the legal search page for free - so they can see what it looks like - and then they have within 24 hours to pay for it (using the 1 year option). Thus, I want the 1 month limitation changed to 1 day. (Right now, it only gives the option of selecting between 1 - 12 months for membership. I want the 1 month membership to be changed to 1 day). [][1] When you register, it will give you 2 options: 1) 1 month free trial or 2) 1 year of advertising. I don’t want the person to be able to have 1 month of free advertising ??" 1 day should be enough time for them to post their ad and see how it looks. ** CONTINUED IN DELIVERABLES ** ## Deliverables ** CONTINUED FROM DESCRIPTION ** The problem is I am a total novice and cannot figure out how to modify the .php coding to change the 1 month to 1 day. I have looked through the .php coding but cannot figure out exactly how to do it. It seems only to work in months. Note: If you already have a similar legal search website available for sale, let me know how much you would want for that if that is easier.. but since I am 99% done and I only spent $29, I figure this slight modification is the best option. Therefore, please let me know how much you would charge to make this modification (i.e. changing the 1 month instead to 1 day). ** Also: Although not as important as the above request (changing the 1 month to 1 day), I would also like a second modification to display the ads in RANDOM order. Right now, the php file uses various criteria to determine which order the ads are displayed in (i.e. the age of the ad, etc). However, I want the ads to be displayed in random order -- so this way people have an equal opportunity to have their ads displayed at the top / not worry about going to the bottom of the list. Thanks for your time. ---- I suspect the primarily thing I need is the single .php file that you modified. I can simply upload it to my site and replace the old .php file with the .php file you modified to make 1 month to 1 day. 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
