If you have much low budget, You can cover all major places in a single day as well.. start from morning at 8-9 from hawa Mahal and then move to Amer fort than to its adjacent jaigarh fort, and lastly u can go to either nahargarh or jal Mahal by the evening. By this you will be able to cover almost all the major places in a single day and you might return the same night. This was my experience when I visited there the previous year.
If you are solo, you can try traveller hostels and you'll find them on Hostelworld website. The accommodation can be as cheap as 300₹ a night for a bed.
