Where to find these service providers?

If you are looking for a website builder for your non profit portal, then there are many options on the internet. All you have to do is look on the internet for them and you will be spoilt for choices. You should keep in mind that the budget cannot be very lavish and you will have to make do with small amounts of funds for this purpose. For a low budget non profit website builder, you can look for someone who has low experience in the field. You will have to be a little tolerant with him and allow him to learn the tricks while working on the pages. This is a win-win situation for both the designer as well as the church authorities. 

Are there service providers operating free of cost?

When it comes to providing service to The Lord, there are many people who do it willingly. You will also find a non profit website builder for free if you look for him or her within the member list. All you have to do is announce this on the home web page or in the church so that the members are aware of it and take up the initiative. The domain will allow for more than one volunteer to operate the website so you can have 2 or 3 experts working bit by bit on the portal rather than putting the burden on a single person. The key is to search for the right person in the right place.
