1-I want to create sub domain by country:

Panama.mydomain.com Colombia.mydomain.com Argentina.mydomain.com Etc

We're providing unlimited licenses for all subdomains you can use freely software. Also you can provide your stores to virtual subdomains with a store module. For example:

visiosoft.mydomain.com

store1.mydomain.com

When I create a store name visiosoft I'll have a company page with my ads/products.

2-      When using subdomains, When I change settings and configurations and designs in 1 site it will replicate to the other sites?

It depends on how we install them. Both choices will be advantages and disadvantages. Technically it's possible to use 1 database for all your sites. But on the marketing side it'll be hard to manage marketing. You create campaigns and ads for different countries.

3-      Will I be able to change individual fields like currency in each country site?

Multiple currencies are supported by openclassify. But you can choose only 1 default currency. If you change default currency and if we use one database for all sites it'll affect all sites. 

4-      Then once the user is in the selected country, I need to create the following sub locations:

2.1.- Country

2.2- State

2.3- City

2.4- Neighborhood à this is important for Real Estate.

I need to import all this data from a csv file. I have all the locations I need on files.

I want to be able to change from 1 country to a different country using a tag in the top bar.

We've location data for all over the world. But if you need to change them you can use either admin panel or you can use the import module to import your CSV file. 

5-      The site must be in Spanish. (if you don’t have Spanish version, I probably could translate it for you.

We use crowdin to translate different languages.

6-      I want to be able to create side menus with the fields I want for each category.

We've a very advanced custom fields module to create custom fields for different countries. 

7-      The site will be multi categories: Cars, Real Estate, Jobs, Freelancers, Classifieds,  Services, Pets, Wanted.

We've 10 level category system for all your category needs. Also we've category data includes 31.000 sub 

8-      Can I change the design of the theme?

We've lots of configuration in the admin panel. Also you can add CSS code in the admin panel. For advanced needs you can change theme's codes.

9-      For the Cars section, I would like to have the MAKE field and MODEL field connected, so for example, when I select the mark “Toyota” it will ask me to select the model of “Toyota” only in the Model Field.

Yes we already have brands and models are connected in categories you can check it. 

10-   Do you have an import csv for categories, sub categories, car makes, and car models?

You can import categories but I believe you wont need import for cats.

11-   Does your script have a moderator function for the ads?

Yes you can moderate ads or you can disable moderation. Also you can disable moderation for just store who paid and get a subscription from you.

12-   Can I use Google Ads?

You can get Google Ads just put the code in ad fields theme settings what you get from
