ITR 3 will be suitable because transaction will be counted as his business & He shall get complete deducted TDS as refund if his total income is less than 3,00,000/-.
ITR 1 is specified for salaried person (Upto 50 Lacs) by Income Tax Department, Income from other sources is additional part of this form. It would be better that you should file as per rule "ITR 3" otherwise It can be defective in future by Income Tax Department.
