Transfer site from Arvixe Host to WordPress Host


We are changing our website Host from Arvixe with Joomla template to WordPress with a WordPress template. I have the business account set up, need help transferring any files WordPress won’t do automatically. I have a meeting with WordPress Rep. 8/11 at 8am for further details. This is a small church website at, small budget, so it’s just a one-time project. Would appreciate any estimate proposals for help so I can give the Board an idea of the costs.
