Migrate from SugarCRM to ZohoCRM

I currently have my CRM managed in Sugar but, I have decided to move it across to ZohoCRM. As such, I will need someone to do a dump of all the data inside Suagr and convert and upload it into Zoho for me. I am unsure about access to Zoho's backend as it is? a hosted service so, all I can find is uploading data through CSVs. Your experience with Zoho or similar services will obviously position you to better understand the process involved. However, the SugarCRM database is sitting onmy webserver so I can provide access to do an SQL dump when required.
