I would urge you to look carefully at leasing costs though. Vans often tend to get a hard life, and leasing companys basically look upon the vehicle basically as 'scrap' after 3 years, or 'nill' value. The amount 'you' pay will be based on this principle. If you are a 'one man band' and look after your vehicles, you're van will last maybe many years longer. You may well be better off 'purchasing' it on a loan.
Leasing and Contract hire are now very complex things with individual 'deals' being designed for 'you're' particular needs. Speak to a recomended lease company and ask what they can do for 'you'. Also speak to your accountant.
Then you can make your decisions.
Good luck !
